When you fall in love, you are listening to your heart.
When you break up your heart is broken, so you got to use your head if you want to get him back.
A broken heart will not let you think straight, so you need to put your emotions aside for a while and rely on your logic.
Here you'll find some pointers that will help you get him back: -Be positive! Even if it's hard, nobody likes a depressed person.
If you want to be attractive to him again, you need to be at your best - be again the person he fell in love with.
-Stop chasing him - this will only put the label "obsessed" on you.
Try giving him some space to sort his emotions - plus the lack of contact will make him wonder what you're up to, so he'll be the one calling you.
-Make the best use of the spare time you have now.
Start doing things you enjoy - buy some new clothes, go to the gym, catch up on your reading.
Do the things that make you happy because this will make you feel and look better.
-Boost up your social life.
Start seeing your old friends, and make new acquaintances.
When you meet new people and see old friends, you'll start seeing things in a different perspective, which is exactly what you need.
-Finally, don't rush things.
Even if you want to get your ex back, rushing him will only make things worse.
Have some patience - if it's true love, you will be back together again.
Doing all of the above, will help you be more positive, which is good for you, and helps you get your ex back at the same time - he'll want to know what happened to you, and when he'll see the new you he'll want to be with you again.
