I wonder what the guys say is a good response when W ignores you.

I think if it's something really minor, ignore her ignoring, just let it go.

If it's a direct question and she's being downright rude, call her out on it. You can't force her to answer you, but you can poke a little fun at her to let her know she's not acting attractively OR getting you upset. Like "oh, the SIlent treatment, REAL mature!" chuckle and walk away.
