(((hugs))) "Therapeutic relationship" is different, you know that. It isn't friendship, the T isn't your brother/sister, mother/father, best friend... none of those and yet... somehow... can be all of those? Your T must always be your T for you. You envision building up to say goodbye and then that's that...but why? You can always return. If you need to you will. Your T will be there, not as a friend, but as YOUR T. That's right where he needs to be for you, it's better that way.
