So this morning me and DP had a blazing argument regarding our DD's second birthday on Saturday and the number of present's I have bought for her. Rightly or wrongly my response was along the lines of well if I don't you won't, which then led to a barrage of well you don't contribute to my kid's maintenance and I already have 5 lots of birthday presents to buy for and 5 xmas presents...(he has five children from previous relationship and one with me). AIBU to not be contributing to his maintenance payments or to think DP would contribute to gifts for our DD?
