I felt a like this before Christmas. DH went away and I felt like life was easier without him here. However I have 3 kids and mine are younger than yours.
DH and I had a chat about things, I suggested marriage counselling but he wasn’t really onboard. He had been moody around then, shouting at the kids etc but he has improved since then, he is trying, and I’m working at it too.
How old are you? I’m mid 40s and perimenopausal and it’s playing havoc with my moods. I’m seeing the gp next week to talk about hrt. I don’t think I was in the right headspace a few months ago to make a big decision about separating or not. I did some budget calculations for living on my own, but I never made an appointment with a solicitor, that seemed a step too far.
It’s very easy for posters to say just leave, it’ll be great, you’ll have a fantastic life but you’ll be the one living with the consequences.
You sound uncertain right now. Maybe you could try individual counselling? Maybe sit down and look at your finances, what you would likely get in a split, what house you could afford etc. and imagine what custody arrangements you’d have, how you would feel not seeing the kids all the time etc. Read some of the posts from single parents on here about the realities and dating, it isn’t all rainbows and roses. Perhaps make an appointment with a solicitor and get an idea what you’d be entitled to.
Then, if you’re still unsure, given yourself a few months off from thinking about it and revisit in 3-6 months time?
