As an extra data point. Not having her get excited about xyz is one thing. My gf from long long ago(just after varisty) would belittle/disapprove flat out freak out if i showed shared something with her that she didnt like or approve.

Show her some video on YouTube about a random topic, sure she doesnt, have to like it. But just hearing the video presenter from another room will be enough for her to freak out 'urghh are you listening to thatttt guy again !!! I cant stand him he is so boring such a **.'

Going on a roadtrip ? You better tune the radio to 'something good' the first time, Else it will be a 1min lashing of how boring,stupid and irrating the person's voice or topic is !

Just ask/say you want to listen to something else, I dont need to hear all the rest.

I never was/is much of a spiritual person, but that ex showed me how the 'room energy' can change in a instant !

Marriage - sure it can be great, but be careful of ending up in a 'military state' at home. Your mental health wont survive it !
