I have a personality crush on someone perhaps, but I wouldn't want to disrupt their relationship with anyone, and thus I let it simmer in the back of my mind. I don't know if I'm attracted to her though, never seen their face. Hence, personality crush. There's a girl though, who I care for a lot. She knows it too, which is why I don't feel the need to exclaim it.
In saying that, I don't separate my online and offline life much, so I don't find it too odd to like people you haven't met, but I do feel that the physical approach is essential when knowing how much you like someone.
I'm really open to people telling me how they feel also, I've always thought that my feelings towards them are immaterial in relation to how they feel about me. Most people have no problem telling their favourite celebrity how they feel about them, despite lack of chance, so why avoid telling a person who may feel the same about you? Crushes have also enhanced friendships I've had when not mutual too, they break the ice in many ways.
