This is the perfect example of what I mean.
You don't know OP, her husband, their everyday life, division of labour or dynamics. Yet you believe and actively advise she should divorce her husband and become a single mother with no idea of the consequences of that to her and her children.
I am a woman and mother of 2 under 3 with a DP.
I can't drive for 12 months due to epilepsy (hence the username) . So my DP does all nursery runs, food shops, pharmacy pick ups etc. He also does all the laundry and cooking and works full time.
I however earn more money that we rely on, do more cleaning and bedtime routines whilst DP cooks.
Without eachother both managing our roles our lives would be infinitely worse. That's how our partnership works.
But how would any stranger off the internet know that? They wouldn't.
Yet like you, they would assume that my DP does nothing. They would have 0 knowledge of the ramifications in mine, my children and my DPs life if we were to split.
So they would be giving advice and encouragement to separate with 0 knowledge of background, grey areas, history etc.
You don't know if OP actually cheated in the past. You don't know if they have a child with cerebral palsy that needs both parents for moving and handling. You don't know if OP is a recovering alcoholic and her DH stops her relapsing. You don't know if OP had a ridiculously high sex drive throughout their marriage and they had sex daily but now she no libido.
You literally do not know anything other than a few paragraphs the OP has written. So how can you say she should divorce him and her life will most likely be much better?
This is why posters get so angry with 'drip feeds'. Because suddenly all the information and advice they've given is completely wrong. But you can't put your entire life in a OP. So there will always be drip feeds.
OP could come back and say 'im in 50k debt due to a gambling addiction my husband is paying off for me and I'm also in a wheelchair so he can't leave until we sort out carers for me and the kids'.
Yet you'd honestly then still feel like divorcing her husband is in the best interest of her and her small children over messages?
Seriously, this is why you shouldn't rely heavily on an internet forum for advice. People have no idea.
