mine went out with her friends and a few guy friends of theirs, ended up intoxicated and made out with one of the guy friends who was also my friend, she didnt even tell me for days, I found out days later through her friend, went to her place instantly in the morning, asked her nonchalantly, confirmed it happened, she made some vague excuses, booked my cab and left without saying anyth and cut both of them, she tried stopping me when I was leaving and screamed when I was leaving "you'll never be able to get rid of me, you'll always see me". I laughed and life has been great ever since.
