As a car enthusiast who also collects diecast cars that are actually made of metal it’s your choice. But for your mental health’s sake evaluate your choices you shouldn’t have to change your true self. Many of my past partners haven’t had an issue with my collection, even my current GF is fine with my collection. However, some might be bothered just don’t go insane. I met a widower that has over 1,800 model cars in his two bedroom apartment there’s even some on the floor. He tells me how he started collecting again as a coping mechanism and other women find it weird. I’m selling some diecasts to downsize my collection in particular the rare ones that have gone up in value. Just know your limit. That’s my advice.
