A girl in Phoenix Arizona Megan, and they are madly in love. I should know, I'm her best friend.
if you really like the girl, you should just talk to your friend. you may never know, your friend might be just fooling around. Don't hesitate to express your feelings to the girl either. if you are meant to be together , nobody can stop it..
"Who's your best friend?"
you just do it. mmk.
First dump her best friend. You're not doing anything to advance on the girl if you're dating her best friend. Next, tell your best friend how you feel. Then tell the girl that you still like her. If she wants to be with you, she will make the choice to break up with your best friend.
don't be friends with him
If they are dating, then how sure are you that the girl is your girlfriend? Talk to her about it; find out what if anything is happening betwen them, and then ask her whether she is really with you or the other guy. Be prepared for some disappointment.
