Most Helpful Girl
law of attraction. thats how all these break up gurus work. someone dumps you, you show them you can have fun (aka vacation with fun people, not sobbing and crying over him!) and they want you back.
But be careful. And think about all the bad stuff that happened too. You don't want to go through the same thing and having him hurt you again. at the moment it's jealousy and he might even think he wants you back. but unless he doesn't make any genuine attempts to get back with you, let it be.
