He tried to 'hook up' with a girl a month ago but swears he never even went to see her because he felt bad?

I am 25 years old and don't really have a family to depend on as they all are unfortunately psychotic or addicts. My friends mean well but I have not really had a lot of time to make really good friends as I have had to work a lot to support myself and had no time to 'hang out'. I'm pregnant about to marry my partner but I don't think that I am in a good situation. Last year I took care of my partner, feed him clothed him and housed him, when I got pregnant I ran out of money and was not able to get a new job since I was so sick, he hadn't been working at all, only living off of me. He just barely got a job, one that I had to look for weeks online for him since he wasn't even looking. I had to move in with him and his parents, all my things are outside there house getting molded by rain or used whether I was asked or not even if they had the same thing, and I am on food stamps to feed myself however my food always goes to the whole family which isn't right or legal but if i say anything they all tell me i am selfish. His family is not rich but are not hurting for money or food by any means. His parents claimed him on their tax return for last year even though I cared for him and he lived with me and I could use the money now obviously and I really don't think that they appreciate or willingly acknowledge the situation that I took care of their son all of last year like he was my child yet now I feel that they look at me like I'm irresponsible to be needing help when really I look at it like i took care of him when he was fine and now he should take care of me especially since I cant do it myself right now and am having his baby but instead of him standing up and really taking charge his parents are having to help which really is just letting me sleep on the floor, and maybe a ride or two a month to the doctor, I don't use a lot of utilities at all. I have concerns about how they may influence my child, they do not pay a whole lot attention to sanitation or providing their kids with the things that they need and seem to enjoy their two year old granddaughter getting away with biting, scratching, and smacking people which says to me that they are wrongly setting her up in life. Most of his family doesn't even speak english around me even though they know how and no one really has tried at all to get to know me, its mostly superficial. He drinks a lot and last night didn't even come home, he does a lot of things like that like getting pulled over on his bicycle for being too drunk one night trying to get to a bar, is starting to take off to go hang out with his friends and doesn't even bother telling me he's going when he knows it bothers me, and his parents don't really do anything or seem to understand what I am going through. He is always well usually very sorry and sweet afterward. He put me through a lot in the little year we have been together and if I hadn't gotten pregnant i would have probably wound up leaving him. Now all my things are rotting in his backyard, my poor dog has to be with my sister who hates animals and costed me 600 dollars when he was a puppy because she ruptured his eye somehow which the vet said meant she had kicked or hit him which she has done many many times to other animals and him included, and I sleep on the floor 6 months pregnant being kept up all night and morning long by his HUGE family thats always coming and going at all hours of the night with no regard to the pregnant girl trying to sleep on the floor, and this pregnancy has been very rough. I feel that if he really cared as much as he constantly claims than he would be doing more to get us out of this situation instead of constantly borrowing money from his parents for partying that they demand back in full even though they know we need to save money for our own home a car diapers, ect., and not supporting me enough by not partying so much wether its with his friends or family. I have a good feeling that I am co dependent from years of emotional abuse I endured from my family and I feel it may have messed with my perception or judgement. What should I do, I really only have him, and that's the truth. He means well, I think his whole family does but I always seem to be surrounding myself with people that really don't treat me very nice or even just courteous which I don't understand as i have made an art form out of being as kind and accommodating to those around me as I possibly could. he literally doesn't think he is doing anything wrong and does not understand why I am upset and at my whits end now, he is outside now with his dad brother who just got out of Folsom prison and his cousin all smoking weed and laughing, i hear them coughing and laughing and soon they will come back inside to play video games and laugh and yell really loud although its 1 in the morning and I was trying to sleep. I pray everyday but, where do you turn whe
