I don't care the mother doesn't have those days off. SHE HAD the kid, not me. Why do I have to live on leftovers?
Because you married a man with children?
Your posts have been super emotive and garnered a lot of sympathy but if you actually read the detail what you’re saying is that you and your DH have his kids 24 hours in a whole week, possibly 48 some weeks - and you think that’s too much?
What do you want the mother to do - have the kids all week and all weekend too so that her feckless ex who can’t be arsed parenting gets to enjoy ALL the child free time and appease his new wife?
Yes she had the kids, but so did your husband - he doesn’t get to opt out of parenting any more than he does.
If you feel you’re doing too much for the kids and he’s not doing enough then THAT’S the issue you need to address.
You seem to be pissed off with the fact he has kids and therefore you don’t get all weekend free (in addition to all week child free) and even say ‘why should it be your problem’ that he pays child support. Well it’s your problem because you got into a relationship knowing he had children and you married him on that basis.
What solution would you like to see? If it’s that he steps up and does more parenting when his kids are there, and spends the time you don’t have the children doing nice things with you and not being ‘tight’ with money (assuming there’s some left over that is) then no, you’re not unreasonable at all. But those issues are about him, not his kids, and those are what you need to focus on when talking to him.
If it’s that you wish he’d spend less time with his kids altogether (when it sounds like he doesn’t spend that much with them really), wish he’d spend less money on child support and overall wish you didn’t have to consider his kids at all because they’re interfering with your weekend plans then you’re being massively unreasonable and should leave and find someone without children.
