My ex criticised my job recently. You're only a . I had to remind him that without me working part time, in a low paid job (worth it for the school time hours), he wouldn't be able to work full time, or at all if his female relatives refused to provide free childcare. He gives me basic child maintenance, and didn't even pay that for years. When he lived here, he gave me housekeep (half of everything, including stuff for ds), which left him with a lot more to play with than me every month. But it always seemed to be me buying stuff for the house, pets etc. If it was my idea I paid, his idea we both chipped in.
He's never once tried to adjust his hours to suit anyone but himself. It was assumed, even when I was doing overtime in my last job, and working the same hours per week as him, that I would organise childcare. I haven't had that kind or freedom or flexibility since before ds was born.
I reminded him that I have the potential to earn a lot more than him per hour, as I did pre ds, that he can't keep a job for more than two years, or get a non labour type job, and offered to go back to work full time, while he went part time, claimed benefits and was the main child career. He just looked sheepish and said no you're okay ta, and left (his face was a very interesting shade of red).
I shouldn't have lowered myself, but I was so annoyed at him.
