exactly a year ago, I drove to a beer festival. Last year, it was my husband, Grandma and parents. My parents had too much to drink, argued loudly and showed themselves up in a crowded pub and I got so sick of always sitting quietly and waiting for it to pass that I interjected - which made it infinitely worse and they turned on me. My husband left a few days later - a good thing - but he used the argument as one of his reasons, that my family were unreasonable.
Fast forward a year, we did the same thing today. And the same thing happened. We came home, and my mum turned into Mrs Jekyll and Rose to something my Dad said in jest, then when I said it was no big deal, she turned on me and said I'd caused last years row and that was why my husband had left me.
Shocked, I went out to my car to leave, and not only did she follow shouting 'Good, go' she also asked for their door key! I told her to sleep it off, and sat in my car until she went upstairs, when I came in my Dad and i discussed it and he seems resigned to the fact that this happens once every two weeks or so.
It's awful. And she is normally a lovely person! What can I do about it?
