How should this be handled?

My girl friend *Trish* likes the same man that hit on me at the festival night; a mutual friend. Surprisingly, she seemed to get angry/hurt when I told her he’d come onto me. It’s clear to her that I’m not interested in more than his friendship and he’s probably not that interested in me either.

However, he’s never noticed Trish as more than a mate and even gone so far as to ask my advice on how to make sure she didn’t pursue him romantically (I at the time thought he was being silly). I wasn’t aware of her feelings, until she got a bit snarky about it, when I told her. Should I just not mention stuff like that to Trish in future, in regards to this man?
