Tell her "Considering everything that's going on right now, I don't think that would be such a good idea."
When you go home, be sure to be on your BEST behavior. Civil, courteous, even-keeled. Do NOT let her pick a fight with you, and do not yourself engage in any angry outbursts, even if provoked.
You're Jesus, and you are to turn the other cheek. If SHE becomes rude, or disrespectful, or beins screaming at you, then you calmly say "I won't talk to you when you're being rude. When you've calmed down, and can discuss this like mature adults, we can continue this," and then turn and WALK AWAY.
And if she HITS you . . . call the cops. Seriously.
