I think this was very inappropriate for the therapist to say to you. He may not have realized what he was saying, may have been trying to show acceptance, or maybe was flirting. I don't know if steering clear of the guy is a good way to go, but if you were uncomfortable with what he said, you might tell him. Or see if he says or does something like that again, and if so, set a boundary that this is not appropriate between a therapist and a client.

Good luck.
