You can win back your ex boyfriend with a little bit of self improvement. Your boyfriend is not going to come back to you if you are a broken insecure person. Guys want their girls to look good. They want to be proud of the girl they present to their friends as a person who can handle well the ups and downs of life. If you are seriously thinking of a way on how to get ex boyfriend back look for signs that he still thinks of you and likes you.
No matter how bad the break-up was, one thing is sure, he is thinking of you just as you are thinking of him. People who moved on after break-up still think of their ex. Some keep tabs through the social networking media like Facebook. Initially break-ups kill positive vibes. Simmering negative emotions will be strong, especially if you broke up with him. This is when you should implement the no contact rule. It takes time to calm down after the storm. Eventually he will realize you have not contacted him. If he is still interested in you he will take the time out to contact you. If this happens you can assume your ex is probably interested in you. Take the hint and encourage him. Call him back, sometime later or the next day. He will wait to see your reaction.
