Pregnant and complicated

So.. my fiancé left me unexpectedly 9 months ago. It’s been pretty horrible.

My friends introduced me to someone whose always asked about me 5 months ago and I wasn’t ready. I was clear about it. We causally hung out a few times. He lives out of state so it wasn’t like I saw him often. I made it clear I wasn’t ready to date but I’d be up to have some casual fun and yes sex.

He flew up and stayed for 3 freaking months and it was a bit overwhelming really. Not stayed with me but tried to as much as he could. He was pushing for a relationship and I was standing ground I wasn’t ready and still grieving. We got in an argument and he yelled. Like yelled yelled. So I told him that really crossed a line for me and I wanted him to leave. He blew up with this whole ultimatum thing if he left he would never come back blah blah —- yea get out. I’ve never handled anyone yelling well and I think it’s unnecessary. He of course the next day text me and said he was sorry but I didn’t feel like that was sincere and I went with my gut. Said that was it.

The next freaking day I find out in pregnant. I waited a few weeks and called him up to meet and told him. He was so excited. He was so sure that meant we were back together. I assured him no that we would be needing to be friends and communicate well as we will be co parenting.. he seemed great about it.

Well fast forward- he’s not ok. He’s now taken the stance no romance no friends no co parenting no father. I haven’t heard from him since.

I know he will come back around at some point but I don’t know when. Or how . I’m nervous about some of his behaviors. He is so hot and cold and back and forth. I’m worried about how co parenting will go.

I’m considering what options I have now. I’m nervous this person I don’t know very well will end up with our child 1/2 time and be completely out of agreement with each other.

Suggestions ? I realize I made the bed blah blah I’m sleeping in it. So those kinds of comments aren’t needed here. I’m wanting to stay calm and as stress free as possible.

I can’t help but wonder what he’s plotting.
