It’s so crazy you brought this up. I’ve been accused of faking interest in the past when I wasn’t and was actually doing the thing on my own.
My last ex did this a lot actually. Great example - he started watching Columbo so I took an interest and also started watching it. Then he like got upset? Told me not to be interested in it at one point?
I had another guy do this too but with hip hop and he waited until we were like two years into the relationship to accuse me of not really being into old school hip hop? Like why. I was literally living with the guy and he would come in the room where I would be listening to stuff on my own. Hell I still listen to Three 6 Mafia and Digital Underground. I even knew about Digital Underground before I ever met him. Like it was such an outlandish claim that I was faking an interest.
I never once faked anything but I’ve gone out with numerous guys who pull this shit for some reason. The only thing that makes sense is they were trying to fuck with my head on purpose.
Now I focus on myself more cause it seems pointless to be interested in things other people are.
