We have been separated for most of this year but spent Christmas together for the DC. STBXH has treated me appallingly during seperation/ divorce and there's absolutely no hope of reconciliation as he has a new partner who he lives with however after treating me with such little respect and kindness he is now going out of his way to 'help' me with things, being overly nice and bought me more gifts this Christmas than the last 5 combined. This is throwing me completely. I am not past the completely blindsided/ heartbroken phase and I just don't know how to take it. Is it just guilt on his part?
