First of all, she most likely brushed off the first two incidents and minimized them as described in this complaint. Sexual assault and harassment have been minimized forever...women are taught to "just deal." Whether she was raped or not, going back doesn't change what happened.
The suicidal ideations began after the alleged rape, not the ejaculation on the back incident.
Being familiar with gymnastics, typically elite and NCAA gymnasts are disciplined, good students, and often grow up very sheltered because of all the time they spend in the gym, missing out on regular activities at school. Ms. Taylor also grew up in a religious family, so between that and her lack of life experience, I think it's pretty understandable how she could have put herself in such vulnerable situations.
