Just been on the phone to the ex
and he mentioned that he's just come back from taking his girlfriend on holiday for a week. When I heard this I suggested that if he had the money to do that, then it would be reasonable for him to contribute something towards DD1's school trip this term (costing a whole eight pounds).
He then ranted and raved at me because apparently he shouldn't have to pay anything towards the children's upkeep as that's what my benefits are for and I'm bang out of order for even asking.
Sigh indeed.
