STBXH and I are average earners. Both on more or less the same salary and he has agreed to pay me £300 a month which I think is fair.
However, I have asked him to contribute half to larger purchases like school shoes and DS's residential trip which is over £300 this year.
AIBU to ask him this? He says that maintenance should cover everything. I am not being greedy but by the same token, I reckon half for unusual expenses would be fair. (I bought Clarks school shoes so not THAT expensive but they are certainly more than DS's normal shoes!)
