Having a lot of contact isn't going to do either of you a favor. I see where you're coming from and why you made the decision; it doesn't make you a bad person. He has the freedom to move on and find somebody else, or continue to wait for you. That's out of your control and should be out of your mind. You've made the decision to focus on you and that is what you should do.

You obviously care about him and if he's a sensible person he'll understand that. There's nothing to say "fate" won't bring you two back together down the road, but today is today. Be there for him if something goes down, but you will need space if you want any chance at getting over him in the short term. Good luck.
