In all seriousness, I do have your problem. I'm rather shy so when I'm flirting and trying to show someone I like them, they think I'm justa nice girl and friendzone me.
But that doesn't mean you will be single forever. Sometimes it depends on the environment you are in. For example that happened to me at school. Now I am no longer at school I don't usually get friendzoned. Come to think of it people usually end up calling the police on me these days ;P
