2 under 2 and a breakup

Hey guys, I don’t know if this is allowed so I figured I would try and post it if not it’s aye okay.

So I’m a mom of soon to be 2, my son is 21 months old and I’m currently 36 weeks pregnant with my second son. Both my kids have different dads. Not like that really matters but my son’s first dad was not the best person to be in a relationship with. So I left when my son was about 2 months old. I stayed pretty much to myself after that and then met my other son’s dad. We will call him bob for this as it’s probably easier. So me and bob started dating when my son was just a couple weeks after turning one and we havnt been apart sense. Well in the span of our relationship things got really rocky we where fighting a lot not seeing eye to eye. A whole lot of shit I’ll admit a lot of it was my fault I was still healing and a lot to unpack. I guess. So we have had issues with this one girl, stocking us threating us following us ect. So we blocked her and she just kept appearing and it was definitely causing some issues with us. So this month (February) I decided that my mental health was declining badly and we were still fighting a lot ect. As well as him telling me he didn’t know if he was going to be at our sons birth ( he dosnt work a job where he has to go other places ect) So we officially ended today but I was wondering if anybody had was I can get through this as I have a almost 2 year old and soon to be having a newborn, has anybody ever gone through something like this? Any other moms with 2 under 2?

- me and my family don’t really get along and there’s ALOT to unpack with that. But just not the best relationship
