Lost girlfriend to a friend... Help
I have this friend whom I know since high school. Well on Friday I went to the Heat game at Hooters with him, his girlfriend, my girfriend and two other friends. They agreed after the game to go to a strip club and we all agreed. Once in there my friend's friend which I had told my girlfriend I did not like one bit started buying drinks for the women and started acting all nice and being the center of attention. My sister and her husband joined us that and we all sat towards the end in a corner. Well my girlfriend started having drinks after drinks and next thing you know they got involved in a game that consisted of giving each other cherries mouth to mouth. I thought they were going too far but then again these people are my friends. Somehow my friend ended up giving my girlfriend a cherry and accidentally grabbed her bottom lip and was too drunk to notice(as they said) which I found to be an excuse to something so disrespectful. My girlfriend had too much to drink to notice and she says she doesn't remember ever touching lip to lip. My sister saw it and told me to forget about her and move on as she thinks my girlfriend is just not good for me. Well my friend ended what was almost a 5 year relationship and all because of that kiss. I love this girl but I don't know what to do.
My relationship with my friend is over because no matter how mucho he had to drink he should have respected me as I respect all my friends and I don't think alcohol should be an excuse. I think if I should forgive him just because he was drunk then we should all get drunk and as long as we're drunk, no stupid thing we do should count right?. I THINK NOT!!
I think he took advantage of my girlfriend and kissed her because she was drunk beyond recognition. My girlfriend does not remember a single thing about the kiss. It was hard for me to tell her or actually convince her that she was taken advantage of since she would never do such a thing as she respects me with all her heart.
My question is:
Should my girlfriend deserve a second chance knowing that they both kissed but she was drunk or,
Should I end a 5 year relationship just because my friend betrayed me in just 5 seconds and kissed the woman that I had come to love?
