NEED TO VENT & SOME RAW UNCUT ADVICE

Hey mamas, so I’m 38 weeks pregnant here. I’m 22 years old and my child’s father is 42. (YES 42 🥴). It was a one time thing and I fell pregnant. For that reason he wants a DNA test and I respect it. He will get a test 🌚 but he knows this is his kid. His family doesn’t even know that he has another child on the way any day now. My son will be his 7th child. Most of his kids are adults except the youngest two. I guess I’m here to ask for advice on how to strictly coparent with him ? He takes care of his kids, he has a good career but he definitely can be childish.

He barely got me anything for our child during my pregnancy because he felt it was too early and he even asked me “what am I gonna do with baby stuff, he’s not even here yet” like what !! He told me that he look at his self like a boss. He don’t like when anyone tells him when to do things, he do it on his time. And I just said “Understood” because I’m not as established as he is so maybe he’s right. Not to mention, just recently I threatened him with child support and he laughed at me and said I won’t get much or either he doesn’t care and that I need his social to do that. It’s hard trying to figure out if he even likes or respects me. On one hand he does whatever for me and we’re cool and next it’s like he’s acting a ass and I remember why I didn’t deal with him throughout my pregnancy. Just recently I had to reach out to him, I kind of had no choice and he did come through and look out but it was ruined because for some reason I got in my feelings about another woman who he says is literally just a friend.

He never done anything with her but he decided to share with me out of nowhere that she asked him for sex. He says it’s probably because she just got out of a relationship and he showed me a pic that she sent laying on her stomach showing her ass, asking him was her but flat. And I immediately got upset maybe it was the sex And the emotions but he said he felt he can tell me because I’m easy to talk to and he can tell me certain things. But I’m not understanding why I’m upset when we’re not together. We joke about it although sometimes I’m serious but I know it may never work. I’m 22 with my whole life ahead of me and this man has multiple kids and I’ll be bm number 5. Not to mention I just shouldn’t care they are both older people and will do what they please and for some reason everytime we argue or his phone ring I bring up her. I feel that I seem weak and I hate it. I don’t want to even care or feel this way let alone give this situation my energy.
