15 Weeks Preg. 1st preg. alone, unhappy..advice please?

This is my first pregnancy and Im very happy that im pregnant and having this baby. But im not soo happy about my life, Im having trouble with the babys father. He doesnt understand how I feel and he keeps spending MY MONEY on stuff he doesnt need. He doesnt like me talking to guys but its okay for us to hangout with girls that he has had relations with. Now he does have OCD/ADD and he is a recovering opiate addict and still having trouble with it. When we fight he always brings up how much he is changing for me, how Im so mean to him, how I don't care about him, how im selfish, stupid and a b****...which is all NOT TRUE. Ill admit I can be mean to him, but when he comments on the weight im gaining or make dumb remarks that hurts me, I feel I have the right to be mean. We also never have sex, he shows me no affection at all, or complements me..I feel alone in this relationship and in this pregnancy. I have no family close by and my only friend I had down here moved away. We live with his parents and his brother, and they also drive me crazy. Every time I tell him something that makes me mad or upsets me about his bro or step dad he defends them, I feel like he doesnt listen to me, or understand me, or just doesnt care. But I always have to listen to him complain about him not being able to do opiates. When we fight, nothing gets resolved, and I stay up all night crying and feeling alone. I dont know if this is depression or just my hormones or if he is just putting me down...advice please?
Thanks.
