You'll do well to check that thought that T is punishing you. Indeed not! It very well could be that his plans changed; yours change that quickly at times don't they? I think they did think of you and called you as soon as he knew, rather than wait until the day before.

Will he have someone for you to call, should you need to, during the time he's gone?
Will you have your couples counseling still, by a different T? So you aren't without total support. And, you do have us here at PC too!
