What do you think about this potential custody issue?

A friend has a botched suicide attempt from 2 years ago on her medical records. All of her therapists and psychiatrists agree that it wasn’t truly an intentional attempt to end her life, but that’s how it reads. (It’s a complicated mess I’m not sure I fully understand.)

She is concerned about how this could work against her if she initiates a divorce. Even if not suicidal, it can appear as erratic behavior and her concern is that she will lose primary custody (or residency) of her children if her husband tries to use it against her.

My response was that she could then ask why her husband felt comfortable leaving the kids home with her every day for years while he worked if he feels she can’t be trusted as primary caregiver. Well, I have no idea if that holds any water. It made sense to me and I was trying to help her feel better.

I have no intentions of seeing an attorney to ask and I doubt she will anytime soon so I turn to my fellow Flutherites. What do you think?
