There are lots of real reasons to decide to leave something or someone, but there are lots of other reasons that are less valid and less real and less about a relationship than our own minds: Fear (of screwing up, of being left, of not being good enough), restlessness, resistance to growing up, PMS, not knowing how to live without drama, fearing that you're getting happy, and happiness is boring. The thing that scared me the most was the knowledge that if I stayed, something was going to change, and that something was probably me. I didn't know what changed me would look like, or if I would like her more or less than I already did. Would I still recognize myself? Would I still be myself?
