I kicked him out

But now he doesn’t even call our children. He left November 30th and hasn’t even attempted to call our daughter or son. I guess he’s doing it to get to me but I hate it for my kids. I’m doing okay taking it day by day with the breakup. It’s almost like he wants nothing to do with the kids since I put him out. By the way he was extremely disrespectful and it was becoming too much. So I had to finally cut the cord on the relationship. Our daughter is 6 and our son is 11 months. Even if he took a few months and then called what kind of parent is okay going that long without checking on their children. Especially kids he’s been in the house with all of these years. Unreal
