I moved to a new town and joined a group. One person appeared to take me under their wing and I initially appreciated meeting for lunch. However, they asked me to drive them to a short appointment before one of our lunches, and during the trip, they started screaming at me because I had taken a route they did not like. This completely rattled me. We arrived on time and I politely said they could drive to future appointments alone. We went on a tour with the group and this group member rushed me around to hide us from them, telling me to hurry so we could avoid certain people. They bad-mouthed the broader group and said, “Believe me they won’t like you.” I have since eased away from this person and they are extremely angry. They have called and angrily accused me of not staying in touch. I told them I’d been busy. I know ghosting is bad but I’ve seen the way they have loudly yelled at their family and others. I just need to be away from them. Is it too tacky to disappear?
