She asked for your opinion; pressed you to actually give it, thus communicating (by any reasonable measure) that she actually wanted your opinion; and then, when you gave it honestly, was unhappy about it? That's horrible.

Looks pretty normal to me. One incident isn't a strong indicator of personality, I think. There are situations where a significant fraction of people want to be lied to in a reassuring way, and these situations can be recognized reliably enough if one has the necessary skills to do so.

I don't think I'd ever willingly choose to be close to someone to whom I'd ever regret not lying in response to being asked for my opinion. The thought of living like that, living with the knowledge that honest communication is basically impossible because any time the person asks me (and presses me) about my opinion, I have to consider the possibility that what they actually want is lies — that this person prefers lies both to truths and to no comment — repulses me.

There are skills that allow you to discern when people actually want your opinion and when they're just asking for reassurance. Wouldn't you rather have those?
