I think the best way is not what you want to hear: move on. If you try to get in touch, he will know you are still around waiting for him to change his mind. If you are moving on without him, he will feel he has to get back on board now or lose you forever.
That said, I think the main obstacle for you is that you still love him. I completely understand how hard it is to let go of love, but the truth is: he might act all emotional about his cheating, but he did it and he chose to break up instead of try and work things out between you. It may have just been a convenient excuse and an attempt to not make you feel bad about the break-up. If he truly cared so deeply about you, he would not have let you go.
As hard as it may sound: you are probably better off without him - at least for the time being. Maybe there will be a time when the two of you get back together, but I would not wait for that to happen.1
