The very first advice I would give you if you are going through the painful breakup period is to get a hold of yourself and avoid going in depression at all costs if you want to get back your ex.
In depression, one tends to act without thinking rationally and end up doing thing that will end up pushing the ex further away.
Getting an ex back after a breakup is definitely not impossible.
How many times have you yourself met, seen or heard couples getting back together after very nasty breakups? The separation often make them realize how much they need each other.
But they don't just get back together by magic.
There are things that are said and ways to behave to make getting back an ex possible.
If you ask those couples who have got back together how they did it, they would probably tell you it just happened or they got lucky.
The truth is that they don't know because they got back together accidentally.
But if this "accident" is studied well, it is obvious that there is a psychology of human behaviour behind it that will help you get back with your ex.
One of the most important strategies (if we may call it so) is to leave your ex in peace.
Don't call him or her.
Don't text message, don't email, don't leave Facebook or MySpace comments.
Just step back and let the other person feel your absence, that's how your ex will realise your importance.
Another "strategy" is don't appear that you are easy to get.
No matter how desperate you may be to get back with your ex, don't show it.
Show as if you are perfectly fine and all set to move on from this broken relationship.
When you do this, the ex will think if he or she doesn't take immediate action, then he or she may lose you for good.
And if your ex still loves you, he or she will try to win you back.
