How do you know if your ex wants you back or if you are really over?

ASK SOMEONE HE'S CLOSE TO BUT NOT OUT RIGHT YOU NEED TO JUST HINT IF HE'S INTERESTED IN SOMEONE AND IF HE WANTS YOU BACK I'M SURE HIS FRIENDS WILL TELL YOU .....OR IF YOU REALLY BRAVE YOU COULD JUST ASK HIM STRAIGHT OUT. ANOTHER WAY IS IF HE'S TREATING YOU LIKE HE DID WHEN YOU WERE TOGETHER (LIKE THE SAME LOOKS OR THE WAY HE SPEAKS TO YOU)
