Update: Cheri's being shut down.
Thank you all for your input. As of yet, we have not had a conservation about her remarks. Having a huge family wedding out of state, we acted as if all was fine and great. I am still lost as to how to start the conversation. Not have sure how she could react. I have played it out in my mind. I look back and I have missed changes in her I should have seen. I think there is more than I thought. Her fault or mine. We shall see. Thanks for all for your advice and thoughts.
