What would you do?

I’m in my last month of pregnancy and the father and I have had minimal contact throughout these months. He always comes around out of the blue to make sure I don’t move on. He’s completely blocked everywhere except regular text, and that is only to avoid problems when I file for custody and child support. I don’t want me blocking all contact to be used against me in court.

Fast forward every time he reaches out it’s never to ask about the baby, mostly to argue with me and my personal life which is the reason why I do not speak to him anymore. I realized he doesn’t care about the baby at all. He hasn’t gone to a single appointment or bought the baby a single item. Yesterday I was in the ER for pain. When I got home I hesitated for a long while whether to let him know or not. I finally decided to message him to let him know. He left me on read and it’s already the next day and no reply. Part me feels at peace because I did my part in letting him know, but the other part of me feels bothered he didn’t even care to respond when it has to do with his child.

Should I continue to update him? At what point do I just completely stop letting him know things about the baby? He only uses the baby when he sees I want nothing to do with him anymore. At what point to I decide well, he doesn’t even care so I’m just wasting my time even writing to him? What would you do??

I come from a close and big family so trying to understand how someone is incapable of caring for their own blood is shocking to me. It’s all new to me.
