What is happening? Please can someone help

I am a singer and have been most of my life, through my music I met a man that was also in the business but more on a local level. We met in a club where we had mutual friends.
I noticed immediately that he liked to brag and name drop, that was actually my first impression of him.
However he did seem like a likable guy, soon after meeting, he asked me to come and perform with his band the following month to which I agreed to sing a song or two. Although he wasn’t exactly someone I would be romantically interested in, we did have music in common so I thought I should give it a chance at least..

He started calling me, writing me on Facebook through private message, complimenting me and making it known that he would like to get involved. So, we made a date…the dinner date went well so we continued to hang out for the next few months.
To be honest after awhile things seemed to take a very strange turn as he became somewhat controlling. He started calling me and telling me that I needed to take certain individuals off of my Facebook page, he felt that certain individuals were just out to flirt with me or worse. These individuals were either fans of my music, acquaintances or musicians that he was basically jealous of. I wanted to please him so I deleted a lot of people. As more time went by, this behavior continued. He started to get bolder with me and basically demanded that I remove even more individuals that he didn’t particularly like. He also made it clear that he no longer wanted me to perform any more but rather be an audience member in support of his band.
On his Facebook page he had a profile photo of himself wearing a wedding ring, although he had been divorced for a few years. He also was friends with his ex’s including an ex wife. There was also family photos on his profile showing holidays of all of them together…. it was obviously ok for him to do this but not for me.

This was a red flag to me and even more flags started waving in front of me when he did not want any photos of me or mention of me on any of his social network pages. The excuses were not only lame but ridiculous. At one point, he broke it off with me and I should have kept it that way. However he returned by texting me and I was quick to allow it to get started again.

After knowing him 7 months, he asked me to move in. I decided to give it a try. At this point I found out a lot of things, he didn’t have a job, no money, he drove an old rusty, loud, junky pick up truck. He lived in a home that was owned by his parents and they lived next door in a trailer. He had no food in the house but somehow always had cheap beer. His parents were in their early 80s and basically took care of him.
I had a full time job and I ended up supporting him…. I bought the groceries and paid for his cigarette habit of two packs a day and he also asked me to buy his beer.

This became his lifestyle and he took full advantage of it. He drank from 8 in the morning until early evening everyday. Not once did he try to help out with anything.

He also seemed to have a fake
love towards me… he would constantly repeat the words I love you every few minutes, like it was a habit rather than what he really felt. He would also always call me baby or honey… very rarely called me by my name.
He never made a move to hold me, hug me or kiss me. It was always me that showed affection.

I started paying more attention to his behavior and I knew something wasn’t right. Once in a blue moon, his band would play so he would get a little money. One of those times was around my birthday, I thought he would at least get me a card…..instead he started an argument with me when I got home and treated me awful for no reason. I didn’t get a card, gift or even happy birthday. I ended up by myself by going out to get something to eat at Taco Bell.

I also noticed that he would still not put a photo of me on his Facebook page or even say anything about me on it. One day I told him if he didn’t start acting like we were a real couple I was leaving. Crying and begging I asked him to put something on his Facebook to make us public, he goes to the bathroom and comes back and tells me we should break up. I was in shock. This would become a pattern where he would periodically out of the blue decide that we should go our separate ways.

But he would always return the same way as before with a text. And we would once again start talking. I would ask him all the time if there was someone else and his reply would be the same…no.

I had came across a letter his ex wife had written asking him to spend time with her and possibly get back together. He had it hidden in a droor. So I always felt like something was still going on between them.

The other bothersome behavior was his secretiveness, particularly with his cellphone that his mom and dad purchased for him.
He kept it close to him like it was an appendage. He even took it to the bathroom, never leaving it out.
The ringer was usually off or on low. At night he kept it in the pocket of his pants with pillows and clothes piled up on it, on the floor of his side of the bed.

Several times I woke up in the middle of the night and turned to find that he was sliding it underneath his pillow. When he awoke in the morning, he would grab it immediately and get a cup of coffee and head downstairs. His unusual behavior concerning the phone was one of our most repeated arguments. I cannot begin to even explain the atrocious lies about everything. He would lie about things that would not matter, just lying to be lying.

I knew he was up to something so I decided to record him while I was at work. What I ended up hearing was unbelievable!
I realized he had more problems than what I ever suspected.
I heard him talking to himself in big conversations about random things. He also would “practice” what he was going to say and then call people like his dad, me , a friend etc… and he would repeat everything that I had just heard when he was talking to himself.
Then things got worse, I heard him making comments and various statements that were sick and sexual as if he was reading a text and responding verbally.
At times I couldn’t differentiate if his ramblings were sick fantasies or if he was actually looking at something or in conversation by text with someone. It repulsed me.
I confronted him with the audio recordings and he stated that it wasn’t him and he didn’t say anything. I asked him if it was his imposter and he just looked at me with those cold dead eyes.

I realized at this point that what I was feeling and suspecting was legitimate. He did not really love me but was using me.
He would start arguments when their was no problem, he falsely accused me of lying or not being where I said I was etc… I recall a few times lying next to him in bed and he treated me as if he absolutely hated me with his entire being. The more I asked him what was wrong, the angrier he got.
I truly believe he did things on purpose to hurt me. He stopped telling me he loved me at the end of a phone conversation where he always said it before. His phone calls to me basically stopped. During a phone conversation, he had nothing to say. It was as if he suddenly stopped loving me.
I never knew from day to day how I was going to be treated and the coldness was bone chilling. He had no feeling, no remorse. I never ever heard him say I’m sorry or take responsibility for anything. I only heard negative things about me and how he wasn’t going to put up with it. I cried, I begged, I poured my heart out trying to please him but nothing worked.
Four weeks ago I had taken my mother to the doctor and I went to spend two days with her, on my way back to his house he called me and was very angry. I had no idea what was wrong but by the tine I arrived at his house, he was falsely accusing me of not taking my mom to the doctor and suggesting I was up to something. I had my mom on the phone trying to convince him etc… there was no talking to him in any capacity. He told me he hated me and wanted me out of his life. The day before he was telling me how much he loved me and was going on and on about it. In 24 hours he had changed into a different person.

I left , returned to my mothers, I blocked him, his family and friends in every way imaginable. I have went complete no contact. Last week I got the usual text how he don’t want the relationship to end the way it did and then gave the list of things I did wrong etc… I didn’t even defend myself, I didn’t respond in any way.
Then two days ago, my ex husband contacted me and told me that he was sent a message on his Facebook messenger from my N asking to please call him that he wanted to try and figure me out by discussing me with my ex husband.
My ex husband didn’t respond to him but blocked him. I don’t know what to expect next or if he will try to hurt me in someway. If anyone can help me with understanding all of this, I would greatly appreciate it.
