Zoooropa,

You seem to swing back and forth to such extremes with your feelings about T.
And it seems that when she does something wrong, you automatically leap to: Its over.

While people here can validate your feelings, no one here can validate that the situation is exactly as you describe, because it involves 2 people, 2 different perceptions, and electronic communication which can be dodgy.

You say you are "angry, hurt and devestated" - is there any way you can put those feelings on hold until you can address the situation with your T in person?

I'm not supporting your T and I'm not on her side. It just seems silly not to learn from what you have experienced in previous ruptures. There can be a middle ground between having a good T and being devestated b/c you feel your T let you down.
