Bf and I are in early 50s and dating 5 months, see each other 3 X a week. My mother died in Oct, so first Christmas without her. He has been separated for 2.5 years from his wife. He has 2 children. He hasn't told them he is in a relationship because the eldest (24) has told him she doesn't want to know about that side of his life and flipped out when told about a previous relationship, he says he can't deal with that again, the younger aged 22 would be fine though. The children are spending from Christmas Eve to 27 with him as their mother has gone abroad and it will be the first time the children have Christmas without her. Both children have boyfriend's. He has called me on Christmas Eve and Christmas day while the children weren't there ; one day they had gone to the shops and yesterday while he took the bins out. Barely a message in between and I can't call him as his children are there. I feel a bit crap to be honest. I am trying to see it from his perspective in that he is thrilled to be with his children but I feel neglected and sad and really like his mistress rather than his girlfriend. AIBU?
