Why don't you tell T how you feel about your roadblocks, and see if you and T can find a way to work as Rohag has suggested, to move them a bit, or make them multi-layered, so some things can get in, but you still feel you have some protection, so it's not giving them up all at once?

Your T must have confidence in you, that you are stronger, and don't need as much defense. I'd take this as a good sign, whatever you decide to do!
