Advice needed! Kinda long...

Not pregnancy related but posting here because I’m in my 3rd trimester and it involves baby.

My kids dad and I are no longer together. I actually have a restraining order against him because he became suicidal with the kids in his care, refused to get help, then started demanding that he get the kids without seeking any care. I become very afraid and felt threatened with how angry/upset he was that he’d do something stupid.

So this is #3 for us, totally by surprise. I was in complete denial for first half of my pregnancy. Especially with everything going on between him and I. We haven’t been together for over a year since before our 2nd was born. He broke up with me in a stupid argument and we tried to make it work but I just don’t trust him anymore and the fact that for that year he chose not get a job or help support the kids. Before #3, things were getting better. He finally got a job, he was helping with daycare(every other week that’s it nothing else) BUT I was very adamant about not getting back together. He’d already been given multiple chances and still wasn’t showing he was stepping up like he should.

So seeing as I was adamant, I had already taken steps to start distancing myself away from the more intimate side of things. I filed child support(when he still didn’t have a job) and I was trying to emotionally and psychically set boundaries which he was very bad at keeping. Every argument and everything always led back to us and not about the kids. He saw he was losing me and I was in between birth control(which he knew) but he took it as an opportunity to screw with things and that’s how I ended up pregnant with #3. He wanted to try to use the baby as a way to keep me, save our relationship and keep me close to him.

Well 2months before I got pregnant, I slept with someone else and he knows. We aren’t together. It’s not really any of his business. Mind you it was a one time thing. We used protection. He didn’t cum.

But now that I’m 7months pregnant and he’s pissed off about child support because he’s refusing to pay and with that comes consequences. He wants to act like the baby isn’t his when he knows damn well it is. He knows he’s the only other person I’ve been with and the other thing occurred months before.

I’m already under a lot of stress because he isn’t helping out and before we didn’t have a daycare bill so it’s been extremely hard. My question is, what do I do? I mean I could obviously care less if he wants to be in this baby life with the way he’s been acting. I mean he wasn’t in our other 2 kids life very much. He’d go weeks without seeing them and only mention how he misses them after 3/4weeks and I ask him to watch them because I have something. But should I ask the other guy to do a dna test? Or should I just make the kids dad do one when Baby is born?

I mean the other guy didn’t find out I was pregnant until a few weeks ago and yes he questioned it but I’m 100% positive that I wouldn’t be 27weeks if we did it end of February.

Judge if you will, I could care less.
