Is it hard to be a single mother?

Some background, I have no family, live in a different state then any of them do but I don’t have a relationship with any of them. I pretty much grew up in foster care. No I don’t receive any benefits from that. I work a full time job and I’m moving into my apartment in a couple of weeks. I’m also 5 weeks pregnant. I have a roommate situation now and I’m paying $900, all that is paid for on my own, as it should since it’s my responsibility. The father and I are together but live separate. He promised to help me move, but he called today saying he won’t be able to because he can’t take his dad’s car anymore. I’m not upset with him but he’s starting to show me inconsistency. It’s like I can’t count on him. Is being a single mom hard? I’m not gonna put him on child support but he already helps with absolutely nothing financially. He’s a great partner but financially he can’t offer me or baby anything. He is very in evolved and interested in the pregnancy though. It is all her ever wants to talk about. Yes he has a good job but he has a ton of bills so he can’t really help out other than maybe $200 every other month. That’s what he told me.

I’m not going to put him on child support, that would ruin our relationship. He would get really mad at me. I wouldn’t hurt him like that unless I get really really broke and genuinely need it and he refuses to help.
