I agree with everyone else -- this person is a crappy friend. If she won't respect your boundaries, she's not really a friend. And the only real way to teach a person who cannot simply do something for someone she supposedly cares about, is to cut it off. Setting up boundaries isn't very effective if they are never enforced.

I'm also puzzled as to why you think you "can't" talk to T about this. I can see why I'd probably avoid talking to my T about this, were I in the same situation, but it's not because I "can't". More because in the beginning, I would not want to exacerbate the "she said this about you" situation, and then I'd probably just wait way too long before acknowledging how much it bothered me. But in the end, this is a person who is supposed to be a friend who is trampling all over your boundaries. If this isn't fodder for therapy, I don't know what is!!

I completely understand your hurt about your time being given away. That's really crappy and I think T should have seen something like that coming a mile away. In general, she should have seen this issue coming a mile away. Usually if I know someone who needs a T, my T will give me referrals for them -- not see the person himself.
