Exactly. ^ I have had times in my marriage in the past when we have been through difficult times, struggling financially, with no help from family, (they were either dead, or had their own shit to deal with,) and me and DH at each others throats/not getting on.
I have wanted to leave in the past, (when it got really bad for a while,) but where the fuck was I meant to go? We had a mortgage between us (house in negative equity by about 10% at the time,) 2 young children, £40,000 worth of debt, and fuck all in savings. I also worked just 2 days a week (after going part time, as I was no better off full time.) Was I meant to scoop up my 2 children, and live in a fucking cardboard box under a bridge and live off cold soup and handouts for the next decade? Derailing their lives, and quality of life, and ripping their family apart?
No. So I stayed through the bad and shitty times, even when my DH was an utter cunt to me and always in a bad mood, did fuck-all in the house (or with the children,) and blamed me for anything and everything that didn't go his way, and made out I was always 'wrong.' I am sure some posters will blame 'depression.' But I suffered that too, and didn't talk to DH like he was a piece of shit I just scraped off my shoe.
Fortunately, things are much better now we're older, and we get on well, (and have done for about a decade since our mid 40s...) and the kids have left some years ago, and we are financially solvent now. So life is good now. But fuck me it was hard going through some of our marriage when the kids were at home/in school. DH was an arsehole half the time, and I did virtually ALL the childcare and housework whilst he pursued his 'hobbies' and worked a lot. I didn't leave though, because as I said, I had nowhere to go. A person suggesting you 'just leave' is coming from a very privileged position.
The most batshit comment I have read on this thread is 'if you want to leave your husband, just take your children and go and live in a houseshare with other women,' or 'buy a house with your sister. And you can live together with all of your children!' WTAF?! 😂
