So stressed cant keep doing it

I'm in the worst relationship ever. The "boyfriend" of 7 years, has done nothing but help me ruin my life from a drug charge I took for him to me living in a house that is not okay. I have a 1 year old baby with this man. Last year I was able to get income housing but dhhs had put my BF on my mainecare and foodstamps well because of that if I get housing he gets to stay with me, and I cant have that. This man has given me a addiction, when I was 18, debt at 19. This year after i fixed my car he broke it by crashing into it and didnt even tell me, right threw My license plate. Than lied about it. He than in january put the cable and internet bill in my name N I Knew Nothing about it, of course he didnt pay it so $300 is now against my credit. I also have a 80 to 100 dollar probation fee. I dont work currently cant because my sister is in the hospital and I help with her newborn baby. He promised and his father that my Bill's would be paid I just had to stay with the baby all summer while he worked. He made quite a bit of money and told me its buried at his fathers. This whole week he gave me 7, 8, 9, and 12 dollars, from last sunday til now. He wont fix the place he wanted me to move into and when my family needed help digging a hole (which is what he does for work) and in exchange would help fix my bathroom he ignored them. My family cant understand why a man who "runs his own business" cant be there todo something when he says he will. That's because his father sets up all his jobs and goes to them with him. I cant even prove any of this because it only happens in the summer. Im 25 and I have only been on a "date" when he was going to "see" friends. From 18 I've been dealing with this than I was a drug addict when I finally got away from it I broke up with him and left and met a great guy than found out I was pregnant. So I went back because he was the father and now I regret
