<human>: My Girlfriend was assaulted about two months ago. We're both in college and she does student government work so she goes to monthly conferences with students from all over the state. She had previously had a relationship with one of the other students (not exclusive) and he was the one that assaulted her. 

I've tried to be as supportive as possible (i.e. Rape Crisis advising/ generally being there for her and letting her know I believe her and still love her). She hasn't felt like she's in a good enough place emotionally to press charges but she has confided in some very close friends that attend the same conferences to keep her safe.

The problem is the vast differences in how we're dealing with this. In all honesty, I lost my temper in a way that made her focus on me instead of getting, better when she told me. The strange thing is that she seems to be taking this completely in stride. I should be ecstatic that she's not completely devastated but she's so nonchalant that it's off-putting. 

The part that I struggle with the most is that she occasionally still talks to the guy. At first she confronted him and wanted an explanation, but now they carry on their half-work, half-friend dynamic that they had before. This would probably be the part where people get doubtful of her story but she's told so many of their mutual friends/colleagues and has been attending therapy so it's hard for me to think that she's lying.

Needless to say this whole thing is fucking with my confidence in a relationship that I see a bright future in. I want to talk to her about my concerns but all of the advice I've gotten from professionals has said to be supportive and not let her think that I doubt her. Any advice on starting and holding conversations or just dealing with sexual assault in general would be greatly appreciated.

Can you summarize the given text in a few sentences?
<bot>: Girlfriend sexually assaulted. I've tried being cool and following professional advice but she's acting very differently than how anybody's said she might.
