I think you are smart enough here. Everyone has this period. If he is with another person, that only say that person might fit him better . It is not about whether you are good or not. It is all about compatibility and who you are.

What do you mean by "move on"? If you mean dating someone else, then certainly I can understand not wanting to date someone else right away; if you mean just making yourself feel better and not dwell on the past, I would say the sooner the better.
