Feelings, emotions, and love aren’t something you believe in, they’re something you either feel or don’t feel right now. You think you don’t believe in them, but that’s just because you don’t feel them.
It’s not that you can’t or that you never will, it’s that romance is just not a part of your life right now. Not really that big of a deal, I spent most of my twenties that way. Eventually you come out of it and evolution takes its due from you. You don’t have to hurry the process up if you don’t want to.
