OP, this catalogue is very bad.
financially, he earns more than you and even with proportional contributions he will still have more money leftover than you and he doesn’t think this is fair.
household, he thinks he doesn’t have to contribute despite expecting you to be 50/50 on the bills. Why does he think he doesn’t have to do anything in the house he lives in?
and he expects daily sex with the above in the mix? He’s deluded.
you are not crazy. He is completely off the charts crazy if he expects all of the above and for you to be happy about it.
if you leave him, he will be paying 100% of the bills for the household, doing 100% of the work for the household, parenting his kids a hell of a lot more than he does now and definitely won’t he getting daily sex without paying for it.
maybe if you explain it in those terms he will understand it. /sarcasm, of course he won’t understand.
whereas for you, ok your household costs will increase which is unfortunate but despite doing 100% of the household stuff it will be less than you are doing now as 25% of the laundry, washing up and mess will disappear. You will actually get some time to yourself when the kids are with him. And you won’t be expected to have sex when it doesn’t suit you.
sounds like a no brainer really. Yes it will be hard but it will be worth it.
