How can a guy be so loving and attentive one minute and the next minute he won't even talk to you? But that is what usually happens when your relationship breaks up. It's frustrating because you feel that if you could sit down and talk with him, you could work things out. But there of ways to get him back without talking to him. Find out why ignoring him will make him call you.
It is only natural that you should want to communicate with him because you are a much nicer person than he is. Or your demeanor is much better than his. Here he is running off, sulking and breaking your heart. Is that very thoughtful and loving of him? Instead of trying to reason with your ex boyfriend, treat him like he is treating you. Ignore him and have no contact with him.
You might wonder how having no contact with him will get your ex to talk to you. There is an easy answer to that. You will be doing what he least expects you to do and he will be confused. The guy that won't talk to you thinks you love him too much to just let him go. He thinks you will cry and tell him you can't live without him. He wants you to grovel and lose your dignity.
He knows he does not deserve such a sweet and pretty woman as you. That makes him insecure and he is afraid of losing you. Making you lose your pride and chase him inflates his ego and make him feel deserving of you. Once he has you begging, he finds he enjoys it and if he does not communicate with you, it will make you beg all the more.
You can make him change his mind and his attitude almost immediately by cutting off all contact and ignoring him. Act like you are over him and you are moving on.
