I would really appreciate it if someone can give me some advice on the following issues. I'm mentally exhausted, physically exhausted, and financially exhausted from his kids and his family. 

Problem One:

I gave up my cozy apartment and moved in with him. I should have never done that. The first red flag was when we were dating is he was driving his mother on long commutes back and forth to work. We missed out on alot of things because his mother would not get a bus, get a drive with a co-worker, or take a cab. He has even left my Birthday party to go pick up his mother. The second red flag was she lived in the apartment over him. She never offered gas money or repairs on his vehicle knowing he was retired early and he would go without to continue paying for all the gas, the up keep, and insurance to  accommodate her. 

Problem Two:

The second red flag was when I meet his two girls. The youngest I was ok with. The other one then was 14. She was rude, selfish, and had a narc personality. I noticed by the way he spoke about them that the oldest one ruled the roost at daddies house. No rules at all. he would cook and serve all meals right to their rooms, they just leave there mess all over the place, leave the dishes in the living room , leave dirty dishes in the bedroom, and he supplied a never ending cupboard full of treats. 

Problem Three:

His loser sister who has been on welfare all her life. She drinks beer like its water and goes threw a case a day. She comes to his place unannounced sits there with her kid all day and drinks beer after beer, bums smokes, she doesn't care if its suppertime she still sits there. Her kid is a brat and will not stay out of stuff. She doesn't correct the kid and if you do she will rip you a new one and throw a big shit show right in your house. 

Today situation:

Like an idiot I gave up my cozy little place and moved in with him. he had nothing when I moved in. His mother would come down stairs and totally ignore me, I missed alot of things because we couldn't go places because she had to work, and he had little money to do anything because his went to buying junk food when his kids came every second weekend and paying Hugh gas bills to drive his mother back and forth to work. So like the fool ,I am, I started paying more and more until I literally had as much as him '"nothing"

I wasn't even moved in three months when his ex couldn't handle his oldest daughter and sent her to live with him. It was a nightmare she moved in and marked her territory as queen bee of the house. Im sad to say but he let her. Everything was now all about this selfish, bossy, annoying narc kid. I couldn't even look sideways at the kid without papa bear making excuses for her or ripping me a new one. It just got worse as she dropped out of school, started hanging around with druggies, stealing everything from the house, smoking pot, pushing her dad around, screaming like a banshee, and neighbors calling cops. We fought no stop and a few times i was told to leave because I hated his daughter and hes tired of my constant complaining, Really?! His other daughter would not come around because she hated her sister. I finally had it and left. Of course, five days later hes contacting me to come back and things will change, They did change he put his foot down and she left and now lives with her loser boyfriend sofa hoping, his mother retired, and he told his loser sister to get out. His other daughter comes but shes  no problem. She know brings her plates out, is nice to me, and I enjoy having her here. So life has got better .. So I thought 

I saved up and bought a fixer upper house, we started connecting and again and I thought the past bs was behind us. NOT! As soon as I signed the papers he announced his mom was moving in with us. i was upset because this was never discussed with me. All of the sudden his mom was now acting like me and her were best friends. The women never even acknowledged me before, Now all the sudden she wants to be my new best friend. she was told she would only be gave a bedroom. he starts getting rid of our stuff. i was ok with that I was excited about getting my house and wanted to buy new stuff. Move in day she comes with everything in her place including the dust bunnies under her bed. The women starts unpacking and starts adding all her dishes, pots and pans, and silver ware into my cupboards. She has her table in my kitchen. i cannot even move in my garage because her stuff is all packed in there solid.

My living room has her sofa, love seat, coffee table, and end tables. My bathroom the same. The women is so cheap she will not even offer to buy a loaf of bread. she eats like a hog. We have caught her listening at the bedroom door. i work nights and need to sleep in the day shes constantly calling for him to do this, do that, I need this, and go get that. Im being woke up constantly. the last time I was woken up was her screaming at him. WHO SLEEPS ALL DAY. more or less he told her to quiet down because I was sleeping. The women is healthy as a horse and walks every morning. She cant do dishes, pick up after herself, and will not cook herself even a can of soup. He caters in all her meals to her. She started bitching to him about me but she was shocked when he told her shes the problem not me. she constantly is complaining about the house this isn't fixed that isn't fixed. All she does is I want, I want, and I want and its never ending. 

She bought her cat with her. My cat is fixed, flea collar, spoiled, the best of all treats and food, and we both baby him. Her cat is not fixed, has fleas, pees all over the house, pees on the furniture, she feeds her cat our stuff, and refuses to change its liter box. My house now smells like a toilet. I have washed and cleaned my sheets so much I had to toss them in the garbage. Her idea to solve the problem is for  me to get rid of my cat. she wont pay to get it fixed, she wont look after it, she wont clean any of the messes it makes, and she wont get rid of it. We got into a Hugh fight and I told him to take his mother and get out. Now the mother is keeping the cat in her room. It cries all the time. Shes being a total witch now. Shes been telling me cry fat and I need to lose weight, Oh don't seat on that lawn chair you will go threw it, you think you could clean the house, and etc 

His sister is coming over more. Shes doing the same things she did before. On the way out she gets passed wads of cash. His mother has money coming out her ying yang. She will use me for anything she can get off me, She will do that same to him. i mean, the woman wont even offer to sping for a loaf of bread. If we go out she asks us to pick up stuff, She has used all my tylenol, drunk all my good coffee, drunk all my pop, and now she is even using my shampoo. I hate her

Thanks for reading this. I have no idea how to deal with this miserable old hag ... any suggestions
