Never make a permanent decision when your tired and full of resentment. I hear what your saying. Its completely valid and understandable why you feel resentment as your life has changed so much compared with your husband and your feeling so alone in your relationship... However... is there ways you can tackle the things you can control first and then decide if you want to stay or leave only as a last resort xxx
Could you speak to him and arrange a night out yourself? Sounds like you need it and it might help him understand what he's expecting of you regularly.
I mean I wouldn’t leave over that, kids are temporary they will eventually be adults and being an adult with parents who aren’t together can be just as hard to navigate as it would be for a child. Your relationship is important and make it clear he’s not prioritising your needs and if you aren’t happy how can you be a great mother and partner? You deserve time to yourself without the kids. I’m not making excuses for him but ask him how he feels being on his own with them both, because men don’t like to admit their in over their heads, my BD used to tell me to “be quick” in the shower😂 but it was only because he didn’t feel confident on his own not because he didn’t want me to have time to myself, sometimes there’s other issues at play.
