It may sound strange to share this idea but it works like a charm for a lot of people: "ignore your ex boyfriend" if you want to get him back. Most people do just the opposite, they spend a lot of time and energy trying to stay in their exes life. They are afraid that if they disappear their ex will move on and find someone else.
The fact of the matter is that if your ex really loved you, it will take them just as long to move on after you as it is taking you to move on after them. They won't just fall out of love with you. You can, if you choose, use that knowledge to your advantage; here's why: If your former boyfriend time and space he may begin to worry where you are and who you are with. This fear might be all it takes to bring him back to you. By taking no notice of him you are forcing him to understand how good being with you really was - and it was wasn't it, otherwise you'd not want him back in any case?
In order to reconcile with someone who has broken up with you one of the most important things to do is to give them the time they need to actually miss you. If you are constantly calling or texting them they will never have time to miss you, will they?
He has to feel the fear of actually having lost you. He needs to face the day to day reality of his life without you in it. This is the best way to get him to the point where he is receptive to trying to reconcile with you.
I know that if you want to get back with your ex, the advice to ignore ex boyfriend may sound dumb, but trust me, it's worked for thousands of others. As long as you are at his beck and call you become nothing more than an annoyance, or worse, a sure thing. If you give him space to miss you he will likely start to reconsider things.
