My mother has been living with me for 10 months! She is becoming increasingly hard to deal with! She is negative about everything and this Thanksgiving she decided she wasn't going to partisipate because my niece her grand daughter is a lesbian! My niece has been with same partner for 3 years. So my mother first boycotted a cousins Thanksgiving Dinner on saturday because the host has gotten into an argument with her once before Then she informed me she would not be attending my Thanksgiving brunch either. She refused to come up and wouldn't talk to anyone including other family members and friends! She just sat by herself til a friend picked her up! Everyone including my niece kept saying what's wrong and I just said I didn't know because I didn't want to ruin thanksgiving for everyone. I felt heartbroken and angry and I haven't talked to my mother since it happened! I have done so much and I feel so mad that she did this to me in my home! She has caused many divisions in our family thru out the years and I am the only one who stepped up to care for her when she had a heart surgery on Dec 31! What do I do! How do I resolve this? I can't even look at her!
