To get your ex back into your life again after the break up is going to take some careful thought and a little effort from you.
Yes, the urge right now is to get hold of your ex as soon as possible and do and say everything you can to make him/her come back to you.
However, this is the wrong way, so don't do it.
What you must do is try to think of what it is about you that made your ex end the relationship.
Once you have established this, the rest is easy.
During the time that you were with your ex, you might have been so comfortable in the relationship that you let yourself go in some ways.
Have a good look at yourself and be honest - what has changed about you? Have you picked up weight, have you become a bit of a slob, do you really care about how you look when you're around your ex? If you answer yes to any of these, then this is obviously what you need to work on and fix, as soon as possible.
Don't forget though, you might have changed on the inside as well, so have a good look at yourself from that angle too.
Now, to get your ex back, you need to think how you looked and how you were as a person when you first met.
Your ex probably mentioned to you over and over, certain things about you that he/she just loved - this is the secret to getting your ex to fall for you again.
Become the person you were when you first met, and more, and your ex won't be able to resist you! It's also easy to get your ex to notice you without even making contact with him/her.
Just go out with your friends as much as possible, and they will let your ex know sooner or later just how fantastic you look.
This will prompt your ex to see you as soon as possible to see what they are talking about.
You will get your ex back so easily now - just be the person your ex WANTS to be with.
