Give it a try. If he won't do it then that's a pretty clear sign of where the relationship stands, and you deserve to be with someone who is in love with you.
If he does run away again, then it's time to file.
I'm sorry; I wish I had a better answer for you. Maybe you taking the initiative will be a wake-up call for him.
