You've probably met one. I have one. Things were good in the beginning. But I've become the butt of every joke. If I can't do something for her I'm seen as disloyal, and when I'm struggling to juggle work, school, and a relationship, she views me as a flake who walks out when in a new relationship. I've seen her be almost an entirely different person with other people and wonder, why won't she treat me like that? But what's interesting is she's awful to her fiancé as well. I don't get it. What's wrong with me?
