I wish I trusted my gut
That's it. Years ago, for probably 2-3 years I felt the want to leave. This person isn't safe, this isn't normal, I never have these issues with others. My mistake was expressing my confusion to them, so they could gaslight me saying "Actually it's normal. You're wrong and shallow for wanting no conflict in a friendship".
I really should've trusted my gut. I say this was a good learning experience, but nah. This was just traumatic.
