AITAH for not congratulating my grandfathers (from my fathers side) birthday?
I am 30 years old, married and have a child of 4 years. Had a difficult childhood were the most help I got was my mother (although I had to also help her a lot) and from my grandparents but from the mothers side. But we lived (me, my mother, my father, my younger brother) in apartment whose owners were my other grandparents (fathers side)
And now fast forward to today, my grandparents (fathers side) kicked my mother out of the house where she lived for 30years (the above mentioned place), called her a freeloader among other things ( she moved in there when she got maried to their son - my father... ). They kicked out her a month ago.
The thing is my mother helped my father a lot as she could, he is an alcoholic and had 2 tumors related to his drinking habit, and he was always lucid enough to acknowledge that , but his parents (especially his mother - an emotionaly cold and narcissistic women who easily manipulates her husband so I put most of the blame on her) never acknowledged that. My mother went back to living with her parents, she was already there most of the time taking care of them.
And today is my grandfathers birthday (fathers side, age 85) and I feel extremely nervous. It doesn't feel right to congratulate him his birthday since he kicked my mother out and said a lot of bad things to her, but also not doing it really affects me more than I thought.
