I actually so so relate to this.
My T, who I was overly attached to to the extreme, stopped being my T 3 months ago -- we are trying to be just friends, but I just had to take a no-contact break from him starting this week to try and detangle myself from him.

I really look forward to the day when like...a whole day goes by without my even thinking of him. I already love that I am able to think of planning vacations without that gut worry and fear about missing sessions with him.
