I'd like this relationship very much! Work, unfettered, finish work, go to gym, then wait whilst dinner cooked, sitting with DC who are doing their homework.
Join in weekly Saturday family time a commitment for the DC, unless something that can be done anytime comes up! Man child.
Tbh, its a worry when even Bluntness agrees with you!
There is nothing wrong with wanting to do all the cooking, all the cleaning, all the finances, its your house and your way of doing things, why would you start moving your finances across to him he has his own to do, but ffs, what fucking TWAT sits there whilst you prepare and cook all his meals for him, and he doesn't say, no, go sit with the DC, you should be putting your feet up, I feel like a wanker sat here taking all the time, its wrong, I will lose respect for you, you need to expect something from me or you're like a housemaid and the DC will get the wrong impression of how 'partnering' works! Not want to be a woman when they grow up, because your division of labour is unfair, on you, and the DC. Once db comes along you will do all that and manage db?
He was wrong to just 'drop' a family commitment, so lightly, but to say he wants out on a particular Saturday is reasonable, or that he doesn't agree with your plan of every sat family time, but to sometimes be a sunday, etc
He needs to pull his weight, you have already been told not to exercise, so he should be stepping up, and can do that with cooking whilst you spend more time with your DC then sat wont be so intense.
I'm sure your DC would far rather your time in the evening for homework help than his, you're their DM, wouldn't you rather do that?
