Kids dad hates my boyfriend

j.

My kids dad and I split up about 14 months ago. I have an 18 month old and a 4 year old. I started dating my longtime friend about 6 months ago. The problem is, my kids dad does not care for him one bit. They used to be friends and some things went down and because of that, my kids dad absolutely hated hearing about him. I’ve told my boyfriend before that in order for us to have a future, he needs to make things right with the kids dad. It’s extremely important to me and the kids dad and I have a good relationship and I want that to remain the same. I can’t have a future with someone my kids dad hates. It’s not reasonable for me. But my boyfriend pretty much refuses to make things right. He says he’s not good at feelings and emotions and doesn’t want to apologize. He thinks it’s a joke. How long do I even give him before I tell him that this isn’t going to work because they don’t get along? I’ve told him so many times that it’s important to me. But nothing changes. And I know if I go to break up with him because of it, he’ll do it. But I don’t think it should come to that. My boyfriend did wrong, he needs to make amends. Does this seem unreasonable?
