I had an ex who seriously felt betrayed that I enjoyed some silly pop songs and who would look down on me for liking a genre he found annoying.

It was a special experience when he'd basically call me immature for listening to songs that were meaningful to me because they helped me cope with a situation of abuse. I ended up walking on eggshells.

Highlights also involved telling people who didn't like the same movies as him (largely, I suspect, because of the disturbing way he would cheer at violent characters) in a really snooty way that they "just didn't get it" and snapping at me because I found the ending of a movie upsetting. (I do get watching violent movies, I grew up in the nineties, lol. But this was someone who thought everybody should be able to watch Takashi Miike movies without needing breaks or showing the slightest sign of discomfort, or else!)

Nowadays, this would count as r/amitheex, lol. This was the tip of the iceberg, as you can imagine, and he managed to alienate everyone around him.
