Wow this happens to me all the time. I mainly avoid them and try to see which one would set a better example and is a good person who would treat me right. Don't pick one immediately because my cousin did that and they were sweet for a few days and then they got into a fight four days into their relationship. And now she thinks he's going to dump her. Be careful. About two または three boys like me right now and I tell the other two sorry I have a boyfriend who is the third person. Good luck!:D
I had this problem so I decided to put them all in a game like the Hunger Games and make them fight to the death and I'll choose the winner (you know since all the others are dead...)!
