Thanks for the quick reply. I didn't save the text messages, if that's what you mean. I suppose when next month's cell phone bill arrives, I could point to the couple of phone calls that I've been able to see so far on her phone's call log, but that's about it.
I do think she would deny it, at least deny that it's been anything more than "flirting" or "enjoying attention." Then again, most people don't have a good understanding of what an EA is (I know I didn't), so that denial is probably normal.
Let me think about this one. I do think that what I will say (and this will be in person, because I want to look her square in the eyes) is "And I do intend to protect my interests here. I don't mind people flattering you, and I'm sure it makes you feel good, but if it goes beyond that, I will get involved, and it will be immediate and it will be forceful. You asked me for honesty, so there's brutal honesty for you."
