Welcome to the wonderful world of love. It is confusing and there's no road map to show you how to get where you want to be. Your post was very well balanced so you know the issues your dealing with. How long did you date? He may be confused as much as you are, not sure what to do but felt the need to be honest. This was a very positive thing he did by telling you, you may not appreciate it right now but will in the future no matter how things turn out. Looks like time is what's needed along with the occasional long talk sessions to keep updating each other on where you are now and where, if anywhere, you want to go.
