You just cannot understand what went wrong.
You and your ex were together for a long time and everything was going absolutely perfectly - that is until he said he was losing interest in you and wanted out.
Now that he's gone, it's really bothering you - he hasn't so much as called you in days - so, how can you get your ex boyfriend's attention fixed on you again? Your ex gave you the message loud and clear - he was losing interest in you.
Why can't you understand what went wrong? Obviously he feels that you are not the same woman that he first fell in love with.
This can only mean one thing - you have changed so dramatically, that you are like a stranger to him.
You need to become the woman he first met, and then you will get your ex boyfriend's attention fixed on you again.
Okay, so how to fix this problem? It's best to start at the beginning, so take a few steps back in time to when you first started dating, and try to figure out what went wrong from then on.
Have a really good look at yourself in the mirror and be honest.
Are you really the same person that you were when your boyfriend met you for the first time? Remember, he didn't know what you were like as a person, but became interested by what he saw.
The picture you presented to him then was a total knockout to him - so much so that he just had to ask you out on a date.
Are you still the same woman in the picture? Did you become so used to the fact that he adored you with all his heart that you let yourself go completely? You took his love for granted and just assumed that he would love you no matter how you looked - good or bad.
You are going to have to do whatever it takes to be able to present that same package to your boyfriend that he first fell in love with.
It will be difficult, and it will take some time, but if you want to get your ex boyfriend's attention fixed on you again, you had better do something now, before it's too late!
