Don't find her attractiveWatch
Sometimes she says things that make me think she likes me as more than a friend. I don't respond and have been clear about where I am at. The thing is, I don't find her physically attractive. It might sound shallow but she is not my normal 'type'. Other than that I think I would probably find her perfect, but is she a perfect friend as opposed to a partner?
Do what you can to increase her social circle. From which, you never know, she might find a boyfriend.
Also you should as a man NEVER be shunned for rejecting a girl, its called preferences and women do it all the time to guys...
