Never mind what is the 'cheem' thing I've told you previously, but
I think you've got more tickling problems on hand...
At this point, there's really no telling what she MIGHT or might
not be feeling for you... But my best bet at this point would be at
most to let her know that your feeling's a little above just normal
friendships (if you wanna hint and 'express' yourself)... If she
truly is already 'feeling' for you at this point.. She should be
able to 'pick up' rather sensitively... But do note that just like
any other ordinary 'confession'.. If she's an 'extreme' person,
there's no denying that you might just 'turn the whole boat
over'.... At least this method would allows you to regulate the
'signal' you're trying to send across...
Personally, I'm not very favourable of your likely approaches...
Reasons being that she's attached; you've pretty much no concrete
ground on what she might or might not be feeling for you; you're
confused over your own thoughts and possible acts...
An aftermath calculates that even if she's having problem with her
bf, it's probably not a wise approach to just step in... Showing
affections is still relatively okay.. Direct 'walk in' intervention
is not... How long have she been with her bf? How have their
relationship been all along...?
And on a more 'social' level... DO NOTE that you'll have to face
the 'burden' of stepping in with an attached girl (failure or
success alike) among common friends...
