Is it natural for a partner to feel disconnected after leaning your partner has been raped in the past?

I just learned my fiance was raped just before she met me three years ago. I feel horrible for her and sad, but simultaneously I am experiencing a sense of physical aversion right now. Additionally, I learned she did not report the person, which confuses me. I find myself being angry about that.

Is it natural to have so many emotions following this information?
