A "get well" card is a common courtesy, as is answering people when they are speaking to you.
Detaching doesn't mean "being an ass."
You are swinging wildly from one extreme to the other. Treat her like you would a roommate, or the mail carrier. That's a good rule-of-thumb (would you not respond to the mail carrier if she was speaking to you?).
I think the card is okay, but nothing mushy or romantic -- just a simple acknowledgment.

Gotcha puppy. and yeah I am swinging from one ot the other. could that be considered a 180 though...or as you put it, is it just being an ass?
I guess if I dont respond to her...that is a way of showing my emotions as well...showing anger/frustration/sour grapes.
And as far as the card goes, I should just sign my name, not sign it "Love, (my name)"? I always sign my cards to her with "Love,"...but that would be mushy/romantic, right?
