Sometimes you become so infatuated with a person that you start acting like them; liking the things they like, just so you can have some sort of similarity/connection with them. Being comfortable with yourself is easier said than done. But if they truly did have a connection with you, they'd accept you for who you are, your likes and dislikes, your creepiness and silly phobias. Just cos he or she likes the same crazy shit you do doesn't mean that you're soulmates. And if they were your soulmates, you wouldn't have to try or pretend to like the things they like because you already would.
