My lovely brother will have nothing to do with my DH family. He has no reason not to get on with them as they are lovely. We are due to go to a family wedding and my brother and in laws have all been invited. My DB will be civil for my sake but it is obvious he doesn't like them. I've asked him on several occasions what is the matter but he clearly is not going to tell me. It makes family occasions very difficult. My DH has noticed it but tells me to leave well alone. There has never been any arguments but there is definitely an atmosphere when they are together
