I swear I am not making this up. Last weekend, my girlfriend of 4 months and I went to a club together for the first time. Upon arriving, my girl began chatting with a friend of hers while I was visiting with a buddy of mine. This girl walks up, puts herself in between my buddy and me, and starts saying she knows me. She looks vaguely familiar but I can't place her so I ask how we are acquainted. As she is explaining where we met, she asks me to take a pic with her. She whips out a camera and holds it in front of us, snapping a photo of her kissing me on the cheek. Then she proceeds to stick her tongue down my throat right in front of my girlfriend. I was stunned to say the least and when I finally separated myself from her, my date was gone. She returned a few minutes later to inform me she was leaving with a friend of hers but I convinced her to go with me. We returned to her house for what turned out to be a long night. She seems to believe that I led the girl on by allowing her to take a pic and as she says "hang all over me". This entire incident took maybe 60 seconds and I say I was a victim of circumstance, that I never saw it coming, and am guilty only of being in the wrong place at the wrong time. Our relationship was going really well but now she says isn't sure she can trust me because I fail to see where flirting leads and she doesn't think we have the same views about what is appropriate and what isn't. I understand she was hurt, I am sorry this incident happened because I really do care about her but cannot do anything to change it. At this point, I don't know if the relationship will survive or not. She says everyone she has told about this, both guys and girls, think I am an azzhole and that she deserves better. My response to this has been that women will always stick together and that any guy who agrees with her is simply trying to curry favor for the purpose of getting her into bed. What do you guys think......did I bring this on myself or was I the victim of a girl with raging hormones?
