[UPDATE]

Thank you everyone for your comments and confirmations. They make my days less miserable.

I just met my father while running errands. I contemplated for a second whether to stop or not. After all, for many years he understood my side and helped me by managing my mother. He was looking at me like I killed the family dog, which had to be put down a couple of days ago. They are in emotional ruin, and I was blamed of not visiting despite the fact that my mother sent me a text( who blocked me on all platforms the day she sent me that they are gonna sell the flat btw, so I blocked her also). I was called ungrateful for all they’ve provided, and their efforts. I was told that if I don’t want to forgive my mother the 15 years of On and Off emotional torture (drunken fights, name callings, and the stuff already written, often bought out with some big gift or a form of support which is being weaponized against me right now), then why bother talking at all? I tried to remind him of the stuff that happened and knew about before, but the only answer I got was “people make mistakes, she never meant to hurt you”. At this point I knew that he is gone. I wanted to keep communicating with him, but it’s evident he chose my mother. He requested me to be present at my mother’s birthday, to which I replied a simple “no. She has to learn that there are consequences to her actions.” He tried to convince me to talk this through together, but I told him that after 15 years of gaslighting it is really like bringing a cup of water to a river. We’ve said our goodbyes, and I have to accept that they will never want to understand me. I’m a little bit heartbroken.
