Hi,
I can relate.
As brutal as it sounds, I think you should both move on.

Hold on, before you freak out.......I think a seperation will crystalize your intentions. And if you initiate it! Well you will be in the drivers seat. Be strong, have a time frame in mind, and be gentle with him. But dont fall for the inevitable charm........just cut him loose!
Nothing initiates a real relationship better than a seperation.
Hey, if it doesnt pan out........it wasnt going to happen anyway.
You saved yourself some time.
