I am looking for advice on how to handle this situation with my SM. I'll be straight up; I find her sneaky, manipulative, spiteful, underhand and selfish. So, I may be coming from a biased place wink. I don't know where to start.
Her and my DF got together about 5 years ago, and from the beginning I was really pleased he'd found someone and felt very keen and ready to welcome her into our family. However, it soon become apparent that she did not see things the same way. We went on a big family holiday the first year, and on one of the nights, her, my Dad, her kid and her D's DP all emerged onto their balconies, while me and DB sat like ??, and they all went off to dinner. We were younger at the time, and found it quite odd and hurtful.
Loads of examples that I won't detail.
She has become close with my grandmother, and out of nowhere, my grandmother is suddenly very rude to me whenever we speak. I don't have much wider family and to me it is devastating. My father talks sometimes about her controlling behaviour and suggests he wants to end things. I am broadly supportive of their relationship, and am always supportive of their relationship when we speak, but find it upsetting as she tries to prevent us spending time together one on one. He has confided, after some years, that she is jealous and insecure, and that he no longer has contact with any friends, upon her say so, which he resents.Their business obvs.
Most recently there has been a big argument. She behaved really unpleasantly and I don't feel able to visit my DF's house again right now. Our relationship is breaking down, slowly but surely. We were previously very close, but this person causes so much conflict that everything feels hard and upsetting and we gradually speak less and less. AIBU?
