Yoyo,

Well it doesn't sound like OW's H wants to be friends with you.

He sees your value and is drawn to you.

How comfortable are you being friends with someone you are not attracted to, but who might be interested in you?

On the other hand, if you start as friends, and feelings develop, it will give you reason to file.

Most of us guys here are jealous that he gets to take you out. ;-)
