Juulie:
I had a similar sitch a few years ago. Visiting coach gets whacked early in the second half. Loses the game by 25 or so. As we are leaving the floor, he intercepts me at the endline and says: "I still think you're a jacka__, and now there's nothing you can do about it". I reply: Coach, you really need to spend more time studying your rulebook." Whistle, whack, his 2nd T, he is now ejected and subject to a two-game suspension. I'd pay $500 for a photo of the look on his face as I put the whistle in my mouth. (Didn't really need the whistle, but the dramatic effect was priceless.)
In the sitch you describe, I'd have dumped the young lady. I take a pretty hard line regarding blatant disrespect from players.
