Not sure if I should feel guilty...

Basically, on New Years Eve I was at a friends party, and one of my mates got seriously, seriously wasted. He's always like this, and is the type of person who just pulls absolutely anyone, even guys, even when he's not drunk. I'm not like this, I don't have that high an opinion of him just because he doesn't treat girls very well. Now I have another friend who wasn't at the party, but who I was talking to earlier. I found out she really, really likes him, even though she knows he doesn't like her back. Personally I think she can do a lot better than him, but I'm not telling her that!

So at the party, I was kinda this guy's "pulling" target for the evening. He kept coming on to me, kissing my neck and stuff like that, and I kept pulling away from him and walking out of the room. Remember, he was so so drunk so I doubt he remembers any of this.

I'm just wondering, should I tell the girl that he was coming on to me? I didn't do anything to make him act this way, didn't react to him, didn't do anything wrong whatsoever. I told her he was seriously wasted and was acting off his head, but is that being honest with her?

Sorry if that sounds jumbled / like a silly problem!
