Is it normal for my friend to not trust any man anymore?

The guy that raped her (taking her virginity) is currently locked up. This wasn't a random stranger, a short-term boyfriend nor someone she just met. It was her playmate from 1st grade. This was someone she grew up with and went to the same schools. Both sets of parents were very close too. She used to see her as a brother.

It happened 6 months ago, shortly after her 20th b-day. He became obsessed with her, wanted her as a girlfriend, couldn't take no for an answer (prior to that, he was getting rejected by all the others girls he asked out) and raped her when he got a bit drunk. She doesn't trust men at this moment nor wants their friendship. This is a normal reaction right?

She's currently feeling the greatest betrayal ever. She really taught she was safe with him, whom she used to refer to him as a brother she never had (since she's an only child).
