Breakup while pregnant.

I’m 20 weeks pregnant. I just went through a breakup with my boyfriend of 2 years whom I’m having the baby with. It originally started out as a conversation about how stressed and overwhelmed I have felt during this pregnancy yet I feel like I haven’t gotten the support I need from him. It took a turn and ended with us apparently splitting up. It wasn’t expected and was somewhat mutual but he’s now blaming me and saying that it was me who wanted it this way. Our relationship was never perfect from the beginning and I’ve been through a lot of heartbreak already with him. He’s not emotionally mature and he likes to gaslight and make me feel like everything is my fault. And I’ve been so upset over this whole situation. Even though I was feeling the way that I was I was talking about it to him in order to try and fix it but he now says that he doesn’t see the point. Even though a huge part of me feels like this is a blessing I’m disguise and it’s better if we’re not together, the other part of me is obviously heartbroken. I still love and care for him and he’s going to be the father of my child... every dream of a little family or happy ending was crushed ya know. He’s just treating me horribly now and doesn’t seem to care about my feelings.. which was the whole issue that led us to this point. I just have a lot of emotions happening. Part of me feels guilty that I brought a child into this at all, the other part feels like guilty for splitting up with him since we are having a baby.. the other part feels relief and the other part is sad and angry that he’s treating me this way even though I’m carrying his child still. I’m trying extremely hard not to stress myself out too bad but it’s almost impossible not to. This is more than I ever thought I would have to handle at once.. Please do not give me judgment. I need advice and guidance and to hear if anyone has ever been through something similar... and how to be okay after so much.
