My son moved out a while ago and prior to that we were pretty close. His partner is nice but quite cold towards us and very much for her own family who all live very close by. Before my son moved out I thought things would be better than it turns out they are. I feel very shut out of his life and cross that he has let this happen. In the past year I've invited them over for meals a few times but either neither of them come or else he comes on his own. I feel like they're not really interested in seeing us much at all. We have been to their house a handful of times. I am so upset by the situation and just don't know how to cope with it anymore. I know I can't say anything to him as I did mention something a while ago and he was not happy with me. I spend hours awake at night (like now) feeling so upset and rejected. I feel like the whole thing has turned into such an issue for me and I don't know how to stay in touch with him other than the odd text. Any advice would be greatly appreciated
