So i havent slept with him in over a year. i thought we we're on the road to becoming good friends. He
d call me to chit chat and id call him to chit chat. we play basketball together. i thought things were cool.
that about a week ago during a party, something out of the ordinary happened. before the party, i called him and shit we musta talked for like an hour; just laughing at any and everything. i get to the party and we speak and he sits next to me on the couch. no biggie, he likes to be around me and i like him where i can see him.
i still get jealous over him giving attention to others and i make damn sure to not go flirting with another guy in his presence. its a respect thing for the both of us. i admit, i keep my eye on him and vice versa. i see him doing quick looks.
so neways, his team wins the game. he is overly excited and 3 strong drinks down. so he disappears and i dont mind cause its a party.
then
all of a sudden, he's behind me and yells in my ear "We Won!" I look up and he plants a wet kiss on me. there's bout 50 ppl in the room and everyone has seen this! all kinds of feelings erupted inside of me.
i didnt know how to react. so i did nothing and i saw out of the corner of my eye him looking at me. i knew immediately, he was regressing and that he was going to hate me in the morning, hate himself in the morning, etc. i hated the expression on his face. he look defeated BUT i just didnt know what to do. ive been trying to figure out what I DID to make him think it was okay to do that. im drawing a blank.
1.) should i call him to talk about it
2.) do u think it was the alcohol giving courage
this happened about a week ago and its been on my mind. not in the sense that i want him to be mine but in a sense that i dont want him to feel bad about it.
i want him as a great friend.
thanks guys. i am chalking to up to over-excitement and alcohol....
