Relationship from hell

I feel like I’m in a relationship from hell me and my so called fiancé have been together for 4 years. 3 of those years we were together he was in prison. I knew him before prison but kinda of stayed away because he’s 9yrs older then me and I was just getting out there in life. Living with roommates working going to school etc. we dated for a year and we broke up then in 2014 we got in touch with each, and that is how we made it here today!! He’s been home for awhile but he’s going back to his old ways being in the streets, doing what ever he wants. now he’s in trouble and could be going back to prison. This whole time he’s been out he hasn’t gotten a job I have been taking care of everything!! He buys food and other house needs but doesn’t help with bills gives me gas money here and there but it’s not enough!! Lately we’ve been talking about having a baby and have been trying for the last 3months but no luck!! I’m starting to think it will never happen because this is who I’m not supposed to be with!! He’s so wishy washy he wants to get a job, he wants to get married and he wants to have a baby!! Then he turns around and is like he doesn’t want the baby he’s just doing it to make me happy!! Doesn’t want to work, doesn’t want to do nothing!! So I’m not pressing the issue any more!! So I tell him you don’t want to bring nothing to the table we can’t be together. I can’t be with you while you get to treat me however you want, while I’m struggling with taking care of everything. He doesn’t get it one bit!! He says he doesn’t want to break up, he wants to get married!! I will never marry him!! I’ve told him that. There is a chance I could be pregnant now and I told him if he wants anything to do with the baby he needs to grow up. I know this sounds bad but my love for him is gone, I hope he does get prison time so I can leave. While he is out he will not leave me

So sorry for the post being so long
