I want to ask everyone's opinion as to when it is better for parents to split?
I am a dad of 2 kids, a boy of 7 and a girl just turned 11.
Their mother is Italian and constantly says how she no longer wants to live in the UK and wishes she had a time machine so she could jump to the time when the kids are 18 and she can return to Italy. In truth she is unhappy here but ultimately she will be no happier in Italy, even her cousin has told her she doesn't know how to be happy. I noticed a change in her from the moment the first child was born, and while she denies her anger and/or unhappiness are related to the kids in any way, I don't believe it.
The atmosphere in the house is sometimes pretty toxic because she is often angry and aggressive, I assume because she is unhappy, she is frequently rude, mean and unpleasant to me, sometimes to the kids also.
I have been putting up with it partly because I know the kids would prefer to live with mummy and daddy, particularly my daughter who I worry would be devastated if we separated, and certainly I think it is better to have 2 parents than 1.
But I also worry that if we separated and we suddenly had joint custody (I assume), whether the kids would pick up her unhappiness, anger and aggression if I wasn't there. But maybe my being here doesn't really change anything anyway, at least in that department? My daughter is sometimes mean to her brother, I assume to try and get in her mother's good books, and I worry that she will end up unable to be happy (like her mother) and worse will think aggressive behaviour is acceptable.
And if I'm honest there is a third reason for putting up with it. I've suspected for years that one day she might walk out and leave us. And maybe she will. Or maybe she won't, obviously I don't know.
So my question is this.
At what point is separation the better option for the kids?
At what point do the kids start to notice and normalise a bad relationship, to the point that it will affect their own relationships in the future?
