She mentions being sexually assaulted by her cousin when she was 12 yrs old.
I don't believe in judging people if you haven't been in their situation.
I do believe in seeking the right help if you have problems with your marriage. I don't know if she did or not. I didn't see her mentioning anything about consulting profesionals in that field before leaving her husband. But then again, communities like the one she grew up in, don't really believe in that either so she might not had a choice.
