Well you've kind of answered your question right there haha!
As you've said, he still loves you and is not over you. You are obviously on a different page from your ex. You want to move on from him but he still mad about you, I mean he wants to marry for goodness sake!
You're going to have to decide whether you end the relationship completely and try to get him on the same page as you or you can give the relationship another go. Relationships aren't easy and they need a lot of work.
But if you're completely over him and you want nothing to do with him then put it to him and let him off gently. Being near him even as friends could cause trouble for the both of you.
Anyway I hope this helped.
