erm... sorry but you both in relationship or just friends?
if you are in relationship...
you and her have to talk, regardless how awkward it is. Will be
uncomfortable... but at least there will be some explanation for
the behaviours and you make a decision to break or not.
Guessing and waiting... really fustrating...
Anyway breaking up is not the end. Both of you still can be
friends.
if you are just friends.
Just be normal, talk to her like how you did before you
confessed.
