Your friend says it's ok because he is your friend, bu tmost likely he is not ok with it and everytime you are with her he will not want to be around and everytime he wants to vent he will bring up the time you took that girl.


Keep in mind if a girl says she has only dated one guy but your freind is trying to get with her and his friend did get with her and she wants to get with you she most likely is lying.
