Boom! IMO that is strength. Don't let her suck you in to an argument which she then spins it on you and makes you out to be the bad guy. I think it is a good opportunity to establish a boundary around. Let her know that if she wants to talk you will be all ears and validate like a champion. If she wants to approach you and yell, scream, etc. that this is not really a conversation and I will walk away. If/when she calms down and wants to discuss you will be all ears.
Don't take the bait, she [censored] you in and her mind it probably just continues to remind her in her head why she wants out. I would also say that if your arguing that probably means you still care.
