I wonder if her sexual assault from high school (she never dealt with it) has any lingering effects to any of this. I guess its up to her to figure out.
Here's my attitude about that- almost everyone goes through some kind of traumatic event growing up. If she went on to a successful career and a happy marriage for many years afterwards then she chose for it not to shape her life, and GOOD FOR HER. So no, it probably has nothing to do with your current situation. My XW was heavily abused by a boyfriend when she was in college including numerous death threats and waking up in the middle of the night to him standing over her with a steak knife poised over her chest. Despite that we had a wonderful relationship for over 20 years and I feel it had no bearing on BD, S or D.
