(LDR) Girlfriend raped. How do I do the right thing?
	
	
		This past weekend my girlfriend was raped by a close friend that she let pass out in her double bed hotel room. The story goes - she had yelled and shoved at him to leave when he first showed up at her room and plopped down on one of the beds but he was drunk and fairly unresponsive. When he seemed to be completely passed out she gave up. After falling asleep in the other bed, she awoke to find herself (partially or fully) naked and him in the bed with her. Unfortunately, the event of her waking up and the state of her clothes/body have changed in her retelling of the story but I can understand why this part (or any part of this) would be difficult to share with your boyfriend.
Now, I've purposefully left out a lot of details pertaining to the events that led up to the incident. None of that really matters since there is nothing she could have done to "invite" or to have deserved being raped in her sleep by a friend of over ten years. Though, if I'm honest, this is something that I'm struggling with. When she first told me what happened, I was livid. I absolutely blamed her to a certain degree. I tried to restrain my anger and respond appropriately, but I ended up pressuring her for details and allowing my tone to become accusatory. It was so frustrating because she so frequently gives way too much trust to her male friends. She would say things like "but, he has a girlfriend" or "he knows that I have a boyfriend and I'm happy" as if these things would prevent a guy from making a move on her. So, while I didn't necessarily agree with her judgment, I always tried to respect it.
For now, I'm just trying to be a supportive boyfriend despite the distance. It's so hard to push down all the notions that she could/should have done more to prevent this. She talks about wishing I was there to hold her or kiss her but - it's so hard writing this - part of me is disgusted with the thought of being intimate with her in any way. It's hard redirecting my anger toward the creep that victimized her.
I'm not sure we have much of a future anymore. The distance alone was hard enough before. I don't know how we (read: I) can get past this. I don't imagine that I'll ever be OK with her hanging out with any of her male friends ever again. That just feels so possessive to say, but I'm struggling so much.
Has anyone been through this sort of thing? How can I stick around and be the support that she needs right now when I'm having so many of my own problems? How do we move on from here? I'm really not sure that I can...
