@VeroniqueB99 How is the parent who stayed the problem?
- Maybe she didn't want him to stay.
- Maybe she replaced him with someone who didn't want to stay.
- Maybe she doesn't know who it is.
There can be a million reasons. Sometimes its him to blame, somtimes her, somtimes nobody. 1000 cases mean 1000 different situations. But simplify it by blaming the gender (or race, religion, etc...) I don't like is something I'd usually expect from people who are politically far right.
