sorry she resorted to this. It's not an unusual tactic so please know that courts have seen it before.
You DO have a lawyer, right? If not, you'll be in trouble so don't be penny wise and pound foolish by not having one.
Simply take the high road. RO, if you are SURE you have given her no reason to fear you, then tell her you are disappointed she'd stoop to this (or she needs psychiatric care).
And hold your head high. Don't dignify it too much with a lot of debate but be clear about your denial. And call your L asap.
