Abruptly moved out last week, mom is weirdly inviting me round for dinner and being nice...

I moved out abruptly last week without telling her and she has invited me round for dinner.

She has been eerily nice to me in her text messages, using heart emojis etc.

I don't know what to make of this. Why is she being nice? And is she inviting me round just to corner me one last and final time and rip me to absolute shreds? What suggestions do you have?

I want to see her one last time so that I can say to the extended family that I've tried to at least maintain some form of a relationship with her.
