If your divorce is not final, then you are still married. I don't date married girls. He might share my views and is waiting for the divorce to be finalized.
Or he may be shy and need you to directly say you want to DATE him. Say the word "date". Just try it. Something nice might happen.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
