When will I get over the fact that he just don’t care

I have two different baby fathers. The first one I was only 19 and we didn’t know each other well. He’s pretty much a deadbeat and comes around when he wants for our daughter. My second though is the the one that has me stressed. We spent 10 years together and I went through a lot with him. The last thing was the final straw for me so I kicked him out. He’s pretty much said Fuck our two children. I am beyond hurt. He has two children from previous relationships and he never walked out on them. He stayed connected with them spends time and money even though he’s not with their mothers. Now with me he’s just walking away from our two because I kicked him out? That’s ridiculous! My kids are 6 and 1. I’ve been hoping he will come around but it’s been 2 months since he’s spoken to them. He’s alive and well but refuse to call them. I just didn’t think he would become a deadbeat since that’s not what he was the 10 years we spent together. I’m so angry now that I would rather change my number and block any family members of his. None of his family reach out either. Not even his two sons and they are 16 and 12 with their own phones. What would you do? Both of our names are on the Birth Certificate. He moved out of state

Edit: I mean his sons don’t reach out to my two kids. I’m not trying to involve myself more if that was the case I would have stayed in the misery of a relationship. He’s not communicating with them even when my daughter calls he doesn’t answer and he sends no money. My oldest daughter father is on child support but doesn’t pay it so I’m still on my own.
