Every relationship I find myself in feels wrong and has ended because of my apathy/aloofness. Like there's a darkness in my core that envelops me whole whenever I think about romance, sex, my future with someone. I'm currently in a relationship but it's getting flimsier by the second, and now we exchange less than 10 messages a day. My desire to be normal comes at the expense of my partners and I only want to spare them the misery of being with someone like me. How do I start caring? Should I be a loner if it suits me best or is it something I should work on?
