<human>: Can you give me the gist of the text in a nutshell?

My girlfriend of 5 years and my friend decided to go to the bar. We all ended up getting drunk, I ended up blacking out completely.

We saw one of my girfriends friends there who is gay. I Remeber starting to talk to him then I blacked out. Apparently we talked about some things I can't Remeber anything I said. 

Apparently we went outside and he kissed me, then I kissed him back. Then I must have walked home. I had no recollection of any of this and I was in shock when my girlfriend told me what happened today.

My girlfriend and I are okay. But I don't know how to process this internally. I never have identified as gay or bi or whatever. I have never had feelings for this person he was just a friend. I'm pretty angry that he initiated the kiss regardless because I was obviously so impaired I could barely stand. But he said I kissed him back and it's something I wanted. I can't process that part i am not attracted to this person. I was blacked out

I feel confused and angry. I love my girlfriend. We are going to get married eventually. And now I think I just confused her, but I'm confused myself
<bot>: got blackout drunk. Gay aquantence kissed me, said I kissed him back. I'm not gay, I'm happy with my girlfriend. Now I'm confused and upset
