When my parents split up it was my mum who left to live with her affair partner, and my sister and I lived with my dad. We saw our mum reasonably regularly when we were small, less and less often as we got older. She always said it was because my dad (who at that time was alcoholic and abusive to her) had said that if she went after custody he would make sure she never saw either of us again, would use her mental health history to discredit her etc. I've never spoken to my dad about it. Its entirely plausible that this is true given the kind of person he is, however my mum is also an unreliable witness and due to her not pursuing contact with us as teens as it waned, and waiting until we were adults before really getting involved with us again and various other factors, not least she didn't take us with her when she left, I'd be surprised if she had actually wanted any custody of us or would have ever seriously tried for it.
Recently watched The Lost Daughter and a lot of it resonated uncomfortably. My mum was never maternal, always treated us like confidantes and friends far more than children even when we were very little.
So I'm wondering - what's it like to be the mum who leaves? To see your kids rarely, or not at all, by choice? I literally can't imagine ever willingly leaving my daughters. And that brings up a lot of feelings about my now deceased mum (who as an adult i had a very close, quite dysfunctional relationship with) and how she felt about me/us. Especially in the light of more and more frequent threads on here where mum's state categorically that they are not depressed or anxious, they just think motherhood was a mistake and they don't enjoy their children. Any insights or views would be much welcomed.
I'm well aware men do this all the time and no-one bats an eye, so don't really want the thread to turn into a dissection of that inequality. It's more that, given that social context and the pressure on mums to stay and assume the responsibility, what is it like to swim against that tide and what motivates it?
