Ex and DD moved out 3 and half years ago. I am NRP but do a 32 mile round trip to take DD to breakfast club 2 mornings and pick her up and give her evening meal and put her to be 2 nights (at her Mum's).
I pay (well) in excess of CSA (or whatever they are called this week) rates, monthly by standing order as a private arrangement - I have never been late. I also contribute by salary sacrifice the max I can into childcare vouchers which are used for DD exclusively (neither of us has other children or partners).
Ex has now asked if I will stump up 50% of French, recorder, cookery, swimming, gymnastics, ballet, brownies. DD has been doing French, swimming and ballet for years, but the others are new.
My initial reaction is to say no - but I don't want to start a shitstorm for the sake of a few quid. OTH she seems to be asking for an open ended commitment to 50% of everything on top of the monthly amount.
Ex is not short of money - bought a brand new car this year (I bought the old 10 year old one off her!), but I am not on my uppers either.
