AIBU to not be contributing towards partner's child maintenance??

[Asteve15]

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?

He is a prick. He should absolutely contribute to his dds gifts.

You should absolutely not be contributing to his maintenance cost. Not your kids? Not your responsibility.

My DHS ex once told him I should pay towards maintenance and give her a higher amount than she currently gets (300 a month) because she wanted a bigger house...she was kindly told to fuck off

It's resentment at fathers not paying for children but expecting non related family to do so.
I have referee to my own own son as sodding very regularly, particularly when he put egg in my hair yesterday.
You need to. Lighten up

Frankola - omg that is the cheekiest thing I've ever heard!
