A bit of background, as I'm not sure if the past is clouding what is reasonable and what is not. I split with DP early this year, we share a young DD together (he has another daughter, I'm not sure if that will be relevant). During our relationship exDP was financially and emotionally abusive, mainly because of his addiction issues and when we split i was left in debt from bailing him out.
Before splitting, exDP was ammicable and initially agreed that we would split costs for DD 50/50ish, each buy her clothes for each house but split the cost of things such as nursery, shoes. ExDP also, informally, agreed that he would pay me a small sum each month for 2 years approx as that would pay off the debt that he was responsible for, even though it is in my name only.
Except things arnt so amicable now (partly my fault, but the reasons I don't think are relevant) the money towards debts has not been forthcoming, exDP has bought very few clothes for his house, no summer clothes at all really so I'm always chasing for things to be returned. I've bought DD trainers and sandals for summer, aswell as a raincoat, hoodies etc all of which I'm fine for DD to wear at her dads, but I'm starting to feel slightly annoyed that I'm the one landed with the additional expense. Some of exDPs bills are in my name still and he's frequently transferring the money late, aswell as messing around with contact times which is making it difficult to pick up extra hours at work.
I'm considering asking exDP to pay child maintenance but I'm not sure if its going to be worth making an already strained relationship even worse for DDs sake?
ExDP has a full time job, and his time with DD is arranged to as to facilitate him being able to work full time plus overtime, some of which is paid cash in hand. I belive he has had a promotion since we split, but whether his delayed earning reflect this, I do not know.
Based on his earnings, and being generous and saying he has DD 3 nights a week (it works out 4 or 5 nights a fortnight depending on whether he thinks I have plans on my DD free nights and cancels), I think I would get around £110 a month. Not a life changing amount of money, but it would allow me to become debt free far sooner, without DD having to go with put days out, swimming etc.
So I guess am I being unreasonable to tell exDP he needs to start paying?
