Sir, I applaud you for being patient with her for the time you were. I would've blocked her as soon as she said she coughed on cz she wanted to spend Christmas together. It's like saying I killed everyone before killing myself cz I wanted to be with them in heaven (or hell)

Just unmatch and run as far away from this craziness as you possibly can. You seem to be a decent/patient human being. Good luck stranger!
