My GF is a DJ, and at some point some dude is talking to her, and he seems like he almost tried to kissed her, or kissed her cheeks. She seemed very annoyed, and then he took a picture with her.

Later he comes and tells me hes a long time friend of her and that they never been together, and was very happy for us. The guy was dunk and fuck, he was trying to brush his face in mine, fucking disgusting. Later when I saw him again he was like "[MY GIRFRIENDS NAME] BOYFRIEND!!" with a happy face.

I asked who he was, and she doesn't remembered as many people want to take pictures with her and so on. Now I don't know if i confront her to discover who the guy was. I also don't know what the guy indicate, if he was jealous, genuinely happy, or if he think hes a great friend being a fan, and she really don't count him as friend.
