I don't know whether or not you have actually been treated badly since your first bit made no sense to me, and besides, we are only getting your side of the story and I am sure she has hers. But yes, I might indeed tell a person they were unreliable (if they were) even if I hadn't seen them in person in a week. Hell, I've told my mom that after not seeing her in person in a year. A week is nothing for a grown up.

I am wondering if your hypersensitivity might be related to your illness, or is this just part of your nature? Because you sound bitter about her not coming to your aid when you don't feel well.
