Thanks Lynn!

Well, I definitely have a wall...er, WALLS, up!
The history with this man...I met him thru a female coworker, who was, at the time, dating him. She brought him to my house for my art, and he seemed immediately smitten with me. That was years ago, and she and he no longer see each other. She has another "boyfriend" now.
That was around 10 years ago, and he has continued to contact me all this time, buying my art, asking me to dinner, which I usually don't do.
He even brought his daughter to meet me one time. She and I emailed for a while, and she said "Dad likes you."
I honestly don't feel any physical chemistry, but part of that is because I knew the coworker liked him, and I just turned myself off to any possibilities. Whether I can view him in a different light...I don't know.
Thanks, friend Lynn, for the feedback and encouragement!
