Hello and welcome to PC!

Things must be different in your country, but it's a red flag that he had you come to the office so many times. It seems like he was maybe fraudulently billing your insurance company by seeing you so many unnecessary times.

The comment about 'hanging out' was very strange. Maybe he was feeling you out to see if you would have an affair with him.

Anyway, just stay away. Delete his contact info. Don't go seee him again.

You aren't the first woman to feel vulnerable and fantasize about an affair. You used good self control. Don't beat yourself up.
