i think you can be your own person and be in a relationship at the same time. being in a relationship is just one aspect of your life and it's a way to learn about yourself and grow as a person. i'm not saying taylor swift does this (she lets it be most of her life honestly because let's face it, she's made a career based on relationships) BUT generally speaking if you're able to have a balance, being in a relationship shouldn't stop you from finding yourself or working on your relationship with yourself.
