Can I just say, I'm from a culture where divorce is frowned upon highly. (Not so much now but it would have been suicidal for my mother)
When my mum and dad moved to the UK and me and my siblings were born, my mum knew if she left him, she would have had less contact, evil in-laws (yes my paternal grandparents are twats) looking after us and she was scared that we would have been turned against her. tbh the way my paternal grandparents talk about her / TRIED to belittle her in front of us spoke volumes that my mums concerns were valid.
I never look back on my childhood/teenage years as fake, I was quite aware they wasn't a loving couple and it was just the way that wives/husbands acted in our culture. Men stay with men, women spend more time with women. My mum would often spend summers abroad with us in our home country with my maternal grandparents and I loved those holidays without my dad.
Day to day life, dad was at work, mum at home, pretty normal.
When I was in university, mum admitted she didn't love my father and just stayed with us for the reasons you give and what she gave etc. They got divorced. Dad married a teenager from back home within months.. have not spoke to me or my siblings and started a new family lol.
I think because there was no domestic violence/torture abuse, it hasn't been an issue.
But if your husband was to become abusive then definitely don't stay for the sake of it, I've seen those cases too.. and the friends of mine who witnessed that stuff have a lot of trauma and mental issues!
