What am I WAITING for?

I was recently introduced to a man that I felt an almost complete connection to.  When I say "almost", it is because he obviously does not feel the same way (or does he?)...

Although we have spoken about being boyfriend/girlfriend, he tells me he is not ready for another relationship like "that" just yet.  Is he scared? 

I am unsure how to go about this--it's been over 2 years now since my last relationship.  I have dated lots of "frogs" in the meantime&am ready to pursue another (this time more healthy) committed relationship.  He tells me to "wait"--that maybe in another month or so he will be ready.

How will I know for sure?

PS:

He is going through the loss of his mother at the same time..

Is this a hopeless case?  You tell me..
