What "overreaction" to something someone said was actually proved valid later on?

I'll start.

My roommate in college was dating a guy she'd been with since HS. When I expressed concern about them forgetting to lock our door at night (especially with the recent rapes reported near by), her bf told me "you are so afraid of being raped, I should just rape you and get it over with."

I told her multiple times how upset I was at this and she justified it and said I was overreacting. I distanced myself from them and told her I wasn't overreacting.

Seven years later, during their marriage, he groomed and molested her two nieces age 5 and 7. They are now divorced.
