I think you answered your own question right there. Even though he didn't call, use this experience to decide if you really are ready to date or not. If your answer is truly no, then don't start something you aren't ready for and may trigger things you aren't ready to deal with yet.

On the other hand, if you do want a relationship - you need to be honest with yourself here - and feel you might be ready to at least start dating, then do not let fear stop you. Also if you do decide to date keep in mind that you will have more "unsuccessful" dates than you will have good ones. The good ones result in a relationship or friendship.
