feeling hurt what next?

Hello My Friends! (I say this line whenever I can – love it!)
I felt hurt after my m-in-law said smth about my late Father. I couldn’t/wouldn’t speak to her for a couple of months. I only spoke with her on the phone once but never said anything about how I felt. I’m not sure how to behave now. She’s coming over. And I definitely want to let her know what happened and set my boundary. “When you say things like that I will not talk to you or want to spend time with you.” Would that be a OK boundry? Not sure. And I expect she’s going to react in total drama style whatever I say, there’ll be tears for sure.
Ok, I shouldn’t have felt hurt in the first place. Still, I just do not want to be around someone who says such things. Something still not right here…?
