basically one of my better friends has liked this girl for 3 years and shes never been intrested in him as anything more than a friend. a couple nights ago we drinking and me and her fooled around. he found out from someone that was there and now hates my guts. i understand it was a **** move but she admits to being all over me and that i was just ****ed up and went along with it, but he dosn't even listen to me or her. ive tryed to help him get over he in the past but that never worked. so basically what the hell do i do?
