Sunny,
It doesn't feel like T is giving up on you at all. Maybe T is trying to help you disengage when the conflict threatens to overwhelm? If you can be "teflon" then nothing will stick. The negativity of your H can stay where it belongs--in his lap--and not yours. You wlll no longer absorb his crap by disengaging and moving forward with Sunny's agenda.
It feels to me, like T is really in your corner, giving you good advice and helping you overcome these past problems and achieve your goal of moving forward.
Stay the course!!
Peace
