For reasons too complicated to go into here, my DP will be spending xmas day with his ex and their DCs. DP and I made this decision jointly as we believed that if we did not go along with his exes wishes then the children would suffer the consequences.
Just before drop off this afternoon his DC said to me "oh, by the way, mummy said to tell you that now you're living with daddy you have to buy him a xmas present from us"
Is this normal or AIBU to have assumed that it is not my responsibility?
(FWIW for the past 2 xmas' DP's DCs and I have made a desk calendar of photos for him - but have never bought a gift for him from them)
