The first thing to know is why he left you. Is it you cheat or he was only thinking you cheat? This might not be easy to solve. If you did cheat, you should examine the reasons why you did it. Maybe both of you should not be together.
Consider if you lied at him when you cheat.You must be aware that you lied to him if you really cheated. Have you told the truth when he asked you about cheating? Or you confessed the truth? Or, another possibility, did you say nothing and then when he found out you admitted it was true?
If you really cheated, you must feel he is hurting. The only way to get him back is to do things to make him feel you are sincere and will not do it again.
If he believes that you cheated and you didn't, there are only so many ways to prove your innocence. If he does not believe you, the chances are small. If there is no trust, would you stay?
If he broke up with you because he wanted to be with someone else, this is also extremely difficult. This is not a good situation. Your guy will never be back once he found someone new. However, there is a silver lining.
Every time you are with each other, be the best. Make him feel you love as if it was your first. And not the girl he broke up with. He may have left you mistakenly, but chances are he believed you had changed from the person he wanted you to be.
Don't do improvements just to please him. But make him see the love both of you had when you first met. Without any threat or any desperate moves, make him feel you want him back. Just be as good as a good friend to him
This shows him that you care about him and not just about getting him back. Now you're reflecting on your ex broke up with you and wishing him back? Not interested on sparing time being on your best attitude.
The vital point in here is to be yourself when you are with him. If it is not working out, it is important to move on.
