Ghosted and idk why...?

It's been about 2 weeks since I was ghosted and here's how it went..

Been friends/fwb with this guy for over 2 years. We briefly tried to make a relationship work and he decided he didn't love me (after telling me that he did) and ended it. We decided to stay fwb/friends after about a 2 month break from each other. That was about 5 months ago. Everything had been going good, hanging out like always. Thanksgiving came around and he spent it with his ex and their son. I had asked him about doing a friendsgiving together, which he ignored and then later said someone he knew had one and how stupid of an idea it is. I mentioned I'd wanted to have one and he got all weird with me and kinda defensive/rude.

We didn't talk for a few days and I texted him again and everything seemed fine. I asked him if he was in a position to pay back some money he owed me (over $300) that I had lent him when he was in between jobs so he could feed his kid. I know he had the money bc he pulled his retirement of $21k out and basically blew it on new furniture and home decor.

He told me he could and that was the conversation for that day. Later that night I asked him if he could talk to me for a while through text because I was having a hard time with some things. He told me no. He sent me $160 through cash app, (and didn't tell me until afterwards). I questioned the amount and told him that he owes me more than that. He hasn't talked to me since. Idk if I'm blocked or what.

A few days ago I found out that I'm pregnant and he's the only person I've been with. We were careful, but something must've went wrong. I dont want a baby, and I know he wouldn't want one with me. He isn't responding and idk what to do. I havent told him that I'm pregnant, just that I needed to talk to him about something important. Should I just move on with my decision or...?
