that happened to me aswell.....funny story, i liked this girl right, and so did my best friend, so he says to me "you ask her, if she says no i will" so i says "alright" i asked her and she said yes, were still goin out, so my friend is like "fair enough,". next day we go to this party thing and he meets my girlfriends best friend, they started going out about an hour later. Now he wont stop thanking me!, its kind of Ironic if you think about it
