4 years deep into insane relationship with female sociopath addict

Hi,
I am brand new to this forum but I can see that my situation is right at home here. I have been involved with a 32 year old female female sociopath addict for right at 4 years and 8 months. I met her at a tattoo shop i worked at. She hit me up after a couple tattoo visits asking if i could loan her money for her electric bill that she had just got fired from her job due to boss hitting on her so she played the part of a damsel in distress like an oscar winner. But soon after meeting her she moved in and the next thing i know she was wanted by the police for trying to steal a can of peaches and a sippy cup from a dollar store. She had missed court and the police were hunting for her. Long story short.. shes put my life through hell and has been arrested for drugs so many times and somewhat gets her sane mind back while in jail for short stays mostly 30 days or less so i know people say just kick her out..well her home address is my home address and i own my house paid for. She knows i am 100% firmly against drugs but while shes back she might stay clean a couple weeks and then always ends up going back off sleeping with whoever supplies her with drugs. Point is she has ran over me so many times and has got physical hitting me 10 times and knows i never want to go to jail for any reason because it would hurt my career regionally. Ive tried no contact and she shows up at my door at all hours randomly after being gone weeks or months banging demanding to be let in or she will hit herself so when police arrive she will have me arrested. Tons of fear in her tactics. She gets violent.. has acted like she is going to commit suicide at times so ultimately i am dealing with a very severe sociopath situation and due to her involvement in drugs and with so many bad people i just want her gone and to stay gone out of my life. Its like she hates my guts doesnt even speak to me other than to talk degrading to any word i say period so im stuck silent in my own home and to make her leave requires hours of her yelling and screaming and getting violent on me as shes done numerous times. Why wont she leave for good???? Ive made the mistake of buying her out of jail alot of times so she just thinks she can run over me and just treat me like a pure dog making me out to be the heartless one because i wont “love her and accept her as she is” so in her mind im.supposed to be cool with her doing meth in my home..not speaking to me EVER.. and she constantly sneaks and steals everything she can and just wont work, is still legally married to her ex husband over 8 or 9 years ago.. just a very bad loser of a human being and very evil to know how good of a person i am and its like she just enjoys the fact that she can run her mouth to me in my own home. Shes just a drug addict loser that never has worked or been responsible. Lost custody of her daughter over drugs over 3 years ago and hasnt done one thing but stay gone strung out on drugs missing birthdays..missed mothers day.. wouldnt even call her own child and with numerous drug charges even since ive known her the police wont put her away in jail….advice????
