He was talking about his daughter and I just sort of like blew him off and changed the subject to us.. I don't talk about his kids and stopped including them in anything. He was talking about having a photo of us and his daughter in a frame, and I said what would be nice is a photo of just him and me. To be honest I think it offended him. 

Everytime he'd talk about his kids, I obviously listen and etc. And the one day he took a cheap shot at me and said he's tired of people (me) who don't have kids trying to tell him how to raise his kids. As all his mates and family have their own kids, his statement was aimed at me. So I turned around and said I'm not in this relationship for his kids. Im here for him and the bub we're about to have. I could care less about his kids because they're rude, manipulative, badly mannered, selfish and just a pain in the arse and I refuse to do anything for them anymore
