Your response sort of demonstrates the point I made above about most people not being attracted to most people.

In a career of 30 years, you found yourself working closely with a total of one woman who you were attracted to and who you thought might be "willing to become interested" in you. This co-worker was your equal, and you dealt with your feelings in what seems like a mature manner that caused no professional harm to you or her.

Where's the problem that needs solving?
