I hear you. I have been experiencing the same thing since I found out that I'm aromantic. It just feels weird somehow doesn't it? I was totally fine with reading/watching romance stuff before I knew I was aromantic. I just assumed I thought that romance was dumb and didn't like it, but then after realizing that I feel no connection to all those things happening in books/movies the stories just feel so weird! I personally feel a bit isolated reading/watching all those romance stuff... Honestly, makes me feel both bad and sad a little bit. I guess it is because I never realized how there is zero representation for people like me before?
Well anyway, I just try to look at the story from a different point of view. Sure, I'm aromantic, but it doesn't mean I can't enjoy stuff that includes romance. You don't have to relate to every single thing a character does in the story to enjoy it... right?
