So i have this friend of mine,we were childhood friends,S.One day she introduce me to her workmate and her date FN.FN and i started off as friends and soon we were bestfriends.Now,FN already gave up on S cause of her,how do i say this,cannot commit to one guy.So as to say,she contacted guys,lots of them,flirting and stuff and even showed FN her conversation with a guy she just knew.

So one day,FN decided to confessed to me,saying he likes me and i said i like him too but as a friend cause he's dating my friend and he told me he already let her go.

Now skip to the day when i finally break it down to my friends that we are in a relationship,S started to hate me,telling me that i stole the man she love and everything,calling me a b**** a s*** for liking my own bestfriend but in the end she's the one who is toying with his feelings.

Few months went by,she suddenly opened up to me that she still like my boyfriend when she herself already have a boyfriend and is planning to get engaged soon.She was hoping that he would come back to her to make him feel what she felt when he left her to be with me.She even told me about the things she used to plan with him when they get married like,proposed on the beach,have kids,live in a huge house and everything.

I don't know what to do.Its like i feel like i betrayed my friend but at the same time i feel like i did nothing wrong cause he is just a date and the guy she plays around with.
