I resented it when every time I got a promotion my (now ex) DH used to reduce his hours. My career took off and I was still left doing all the housework and childcare (we had a childminder to pick up the slack) while he did less and less for minimum wage.
Now we’re divorced and he pays no child maintenance because he thinks I don’t need it and he has only enough to just live on. I have the kids 100% of the time. Yes I resented him.
I‘m now with someone who earns the same, does 50% of the housework and helps look after kids that aren’t even his own! Night and day!
