I see a lot of LTB. When in reality, very few women do. Which makes me think people are very happy to advise on a "do as I say, not as I do"
There was a poster a while back with 3 young DC, and essentially the husband was a lazy sod. She was unhappy, but no DV or anything extreme, basically he was like having a 4th child. He covered all the bills, mortgage, had a decent job. She was SAHM, no real option to work around 3 children of that age, even if she did the childcare would be extortionate, so if she left she'd have to cover all that, plus her own house, would barely see the DC because she'd have to work so many hours to cover the childcare, and then some. And it was all "life's too short, LTB, you'll be so much happier"
In reality, what most would do, is stick it out until they were at least all in primary. Yes it's not ideal for the tale of "happily ever after", but many women are in the situation where the inability to work (at that time) would mean their finances, housing and childcare options would be far worse if they were on their own. For both her and the DC.
Yet the posts are all LTB. "If my DH ever behaved like that, I'd be off." I just think, yeah, easy to type. Just give up the family home, have to rely on a tiny income or benefits, get run ragged as the primary carer of all the children with a break (if you're lucky) every other weekend. That's what all these posters would of course do, without a second thought
