I see where you're coming from, but that doesn't explain the men who realize "this woman is crazy, I can't let my child(ren) be left alone with her" and they take their kids and dip.
I know a woman where that was her exact scenario. She's close with her dad even though he has flaws(got caught up in the system
) because he made his daughter a priority. He knew what he'd be setting her up for if he left her alone with her mom.
If you married the wrong person, your child should not have to bear the brunt of their resentments and toxicity. You're choosing your peace over your child's if you dip instead of constantly making efforts to get your child to a safe place. Your child didn't have a say in who their mother or father would be. You owe it to them to keep them safe as one half of the reason they're even here(something they couldn't have even asked for).
Two adults weren't ready to be parents and were not compatible with each other. An innocent child should not have to pay the price of their parents failures.
