What am I doing?

Sometimes I wonder what I am doing. I was cleaning up my computer and reading through old emails - always dangerous.
The last post was found in an old email and seemed to strike a nerve. I couldn't stop thinking and of you and that resulted in me contacting you.
So you replied to my email and I replied to yours. After a few emails back and forth the phone call was made and we talked for 4 hours.
What am I doing? Am I prepared to be hurt again? Should I even think about this - do I dare go back?
