While it is The Guy's bad behavior that's causing the problem, it IS The Girl's responsibility since she introduced him and is the acting link between The Guy and The Guild. Given that she seems to not be taking any action, I'm guessing she's the type who is nervous about coming out and telling The Guy "stop being such an ass!" What she NEEDS to do is get over it and give the guy a wake-up call, or he'll ruin things for her in many future situations. She needs to tell him that his behavior is unacceptable and point out where he went wrong. She needs to suggest to him how he SHOULD be behaving, such as not holding down the push-to-talk button and screeching in vent when he gets nervous. Of course, this could go 2 major ways... 1) He'll decide she's the enemy too, which I think would ultimately be better for her to not have The Anchor.. er.. I mean The Guy... tied around her neck. 2) He'll realize that he really IS making an ass of himself, and at least ATTEMPT to improve. But this has to come from The Girl, since any advice from The Guild he'll likely just brush off as THEM being the jerks. At least there's a CHANCE he'll listen to his girlfriend.

Overall, it looks like a messy situation, and I still think The Girl is better off without him. If he can't handle the social interactions of a casual raiding guild that's willing to hold his hand, then I can't imagine he's pleasant in real life, either. Either way, The Guild should just explain to The Girl why they won't be bringing The Guy along with them, and wash their hands of the situation. If she truly is their friend and an avid raider, she'll understand.
