A few things. I take issue with your "Denver school s*ck" claim. My sister is a teacher in Denver. (mostly kidding)
I disagree with 25 to an extent. I think whether you did something wrong by flirting (yes call it for what it was) depends on your motivation. If you were doing it to "show" W that you still had it, You were wrong and you push her button. Would you have done the same thing with two unattractive, overweight women, what about two grandmas? You went out of your way to tell us they were attractive. Relevant? maybe.
I agree with 25, that you W has to be able to deal with this. Maybe now and in her face isn't the best time and place.
