1. Stop Pressuring !!!
Accepting the fact that they no longer want to be with you, is the first step in getting them back.
Trying to make them come back (the way you've been doing) only puts up a wall of resistance for them to push against. 2. Terms of Agreement
Agree with their reasons for leaving you, and sound sincere when you do it. Everyone loves to be told they're right.
3. Don't Call !
STOP THE PHONE CALLS !!! Let them call you, but limit the length of the call (3 to 5 minutes). During the call, try to talk about light, carefree subjects like weather, movies, etc. If you miss a call, be sure to return their call.
4. Be a Busy Bee !
Don't let them feel as if your waiting around on them. Live your life, reconnect with your longforgotten friends, pick up a new hobby. If for some reason you can't be busy, at least appear as if you always have something to do. (This works especially with phone calls ! ie "Hey, it's nice to talk to you, but i gotta go workout, later")
5. Be Desired (or look as if you are)
Nothing works better than one of his/her friends saying something like "Hey ! I saw so and so at the movies with so and so." This is one of the best tricks. If you can't find an actual date, take an attractive relative to dinner or movies.
