I feel like if I detach too much, she will think that I do not want to be with her.
Very, VERY common misconception that nearly everyone thinks when they land here. She KNOWS how you feel about her, trust me -- it oozes from your posts, and I'm sure she feels it even moreso. But that's not the important part of it -- detachment is for YOU. It's necessary in order to get thru this phase.
