I would have punched him after the first touch/grab. Unwanted touching is grounds for self defense. Your "best friend" is an idiot to take her boyfriend's side on this when he is clearly in the wrong. Good riddance to them both. Hope you and your boyfriend can find new friends who aren't douchebags.

No offense but... If your so called "best friend"was willing to blame you for being sexually assaulted, you are far, far, FAR better off, away from that pot of crazy. That shit sounds like some anime yandere levels of wrong. And just to say it, because people don't say it enough: What you wore didn't give him the right to touch you, anything you might have did (accidentally or on purpose) didn't give him the right to touch you, and the only thing that would have made it okay for him to touch you would have been you giving him the go ahead while in an unaltered state of mind. His attempts to shift the blame to you is unfortunately extremely common in sexual predators (which, this guy's actions definitely mark him as either an actively hunting one, or someone who is about to become one) and is also a complete and total lie in his part. I'd suggest letting people know that he's a creeper, and possibly even pressing charges if you are considering it- he might leave you alone, but chances are high that he'll target someone else. You have my empathy and compassion for going through this, and I hope that both you and your boyfriend find other, better, people to be friends with.

Those weren't some very good friends if they are going to blame you when he was the one being the pervert. At least you know now they weren't really good friends.

At least now you know their true colors. You and your boyfriend deserve way better friends than that. Unless he lied to her about what actually happened, you're better off.

What would make him believe you wore what you wore "for him". You are better off without the both of them. Sorry he's probly messed with your best friends head so much she's out of touch with reality. Maybe try one more talk to see it your way? but you're still better off without them and your relationship with your boyfriend can grow from here.

Your boyfriend is awesome for cutting ties with him because most would blame you for what happened so it's good your boyfriend knew he had no right to touch you like he did. FYL

Dear Men of the World: Our clothing does not give you the right to touch, stroke, grab, or maul us. Unless we have given you permission, keep your mitts off us. If you "can't help yourself" at the sight of a scantily clad woman, that says more about you and less about the woman you assault. As for you, OP, I'm sorry you and your boyfriend lost friends because of this douchebag, but good on him for believing you, and screw them for blaming you for Butt Grabber's actions.
