Feeling frustrated

My boyfriend and I have been together since November. since we've been together I have paid for everything all the bills and everything. He's told me a few times that he's had a job but I've never seen any money or help come from it. I'm struggling to keep a roof over our heads and he knows that. But I don't see him doing anything to help but sit on his ass and do nothing ask day while I work and my parents help pay my bills. My parents lost their house because they've been helping me pay rent. I told my boyfriend that nothing is going to fall into his lap or be handed to him he needs to be active in looking for a job. My parents are at risk of losing their new apartment because they're helping me. My boyfriend says he has a guarantee job at Walmart they're just waiting for good back ground check. We've been waiting a week now. I'm trying to get more hours at work but I'm almost 12 weeks pregnant so it's hard. I just wish my boyfriend would grow up and be the man he claims to be. I called off the wedding because I don't have the money to pay for it anymore. And he's not helping me and he's waiting for Walmart to come through but what if for some reason it doesn't. When I try to talk to him about money or bills he gets pissed. I feel like I'm in this alone like I'm going to raise my two kids and this baby alone because he doesn't want to grow up and take action to support this baby that he helped create.
