I see every relationship as a learning opportunity about myself, who I am and how I “do” relationship.

Examine why things have not worked, what was your part in this and what was his.  You already pointed out your insecurity and fears.  You have experienced his fears; his lack of communication and commitment.

You have experienced his actions/non-actions in wanting this relationship.  Wake up and smell the coffee and then proceed accordingly.
