I've started dating this wonderful guy, we've been together for 6 months and talking about moving in together. He has two boys 16, 8 and I have a 5 year old. We've met each others kids and the youngest boys are great together. However the 16 year old wants absolutely nothing to do with me or my son. His dad caters to him and is saying he's giving him time. We talked about talking to him since we are trying to move in together but has yet to even bring it up to the 16 year old. If we go out for the weekend, he will invite him but he won't want to go.
