Think over his decision to back former partner. For a start, clearly decide whether you really want it. Maybe you played affected pride or fear of losing one. If you love this man and realize he made a mistake, take action.
Try not to disappear from his sight. Surely during your relationship you have many mutual friends and acquaintances. They will become the reason for your meetings. Birthdays, anniversaries, weddings and other events, the celebration of which you're both invited, will help you to see and not forget about each other.
Remind about yourself rare calls. Shared life means shared problems. And after breaking up they don't disappear immediately. They will be an occasion for periodic calls. Leaking faucet, broken computer, search one or another thing in the house - all this is a reasonable reason to contact your ex. Say Hello, quickly ask for his deeds and go directly to the point. If he offers his help, do not give up.
Show that you have changed. If you broke up, it means that something in you is not satisfied. Work on yourself and be sure to demonstrate that you have become another. He didn't like your Hiking in the cafe with friends when they call you night mention that you are at home; it did not suit that constantly sit at home - buy a subscription to a fitness club and enroll in foreign language courses. It is important not just to lure the former and stay with the former, but really to do something that this time the relationship failed.
Get a fan. There is nothing better to attract the attention of the former than the new man next to his woman. Not the wild play of passion and love. Just show that you are able to move on, to find a man who will get all of what he lost. Jealousy is your best helper.
