It sounds like you're struggling with some tough things right now, and I know how hard that is!

Just a little outside perspective...your T's perceived distance on the call may have had absolutely nothing to do with you...she may have just been busy or distracted with getting ready to travel.

In regards to the email - my T did the same thing to me not too long ago...it occurred to me that maybe she had just grabbed my file and looked up my email address on that, and it still had my old email. Or maybe she grabbed an old email to reply to rather than a new one. Something similar could have happened with your T. It may not have been intentional, just that she was in a hurry.

I hope you and your partner can resolve things. You know that you have a support system here on PC at the very least!
