First and foremost for my theoretical mate: She's a Christian.
From there, I would prefer she's something of a geek as well. Smart, pretty, at least a passing interest in video games. Very similar to DaDun's description in a number of ways, actually.
I already have a perfect template down, but she isn't interested in me, so I have to somehow find a personality clone of her out there or something. 
EDIT: Before someone comes along and points out the obvious flaw in the previous paragraph, I'll clarify: Personality clone with the one major difference being that she actually DOES love me.
