This starts with a friend of mine, let's call him C. After I met C I kind of fell in love with him, but I got over it (more or less) and we've been good friends ever since.
I now have a boyfriend, and... Well, it's recently occurred to me just how similar he is to C. Personality, appearance, the lot. There are a few things about my boyfriend that irritate me, but they're all qualities that C doesn't have.
So, I think I'm going out with this guy just because he's a lot like C, even though I'd really rather be with C himself. That can't be healthy, can it?
