I have a DD14 with my ex. He pays me £170 a month. He doesn't help with school uniform, school trips, school equipment, school dinner money, extra curricular costs, haircuts. Doesn't take her on holiday. Has her 4 over nights each month, sometimes 3, and 2 dinners.
My DD eats me out of house and home, and is starting to need things bought for school as doing GCSE's. I'm basically running out of money each month and having to ask my parents to help out with the purchase of some things for her. They are more than happy to but have said I should be asking my ex (I think he'll say no).
Me and my ex both work full time. He lives with his wife and her child, it's just me and my DD here.
Would I be unreasonable to ask him to help out more, or should I accept that the £170 I get from him is enough?
