My sister is the only woman I've ever known to give up custody. At the time of the divorce, she thought she was going to be the next big country singin' star and didn't want the responsiblity of the children.L3: It sounds not like the mom gave up custody but maybe even relinquished her parental rights, or at the very least, never had any visitation.
So she abandoned her children. That is very different than not having custody of your kids. Plenty of dads have been denied custody of their kids but they manage to stay in their kids' lives.
THe small number of cases that I'm personally familiar with in which the dad got custody and not the mom, 100% of them = mom has serious mental health issues.
I thought it was pretty selfish and stupid of her to do that, since her ex is a total ass and spent his time at home (living with *his* mother) locked in his room, smoking pot. The kids got no attention from him (luckily, his mom was more present in their lives) and my sister tried to be their friend instead of their mother.
They're pretty f*cked up young people today.
