GTO, here is what I see as signs of attachment:
-You care about what the OW sees or thinks
-You care about what the coworkers think of the OW and about you
-You feel like demanding attention from your H

I've been there, and sometimes I still go back to that dark place. But by definition, this dark place cannot bring you happiness. You need to embrace life and the only way is by continuing the detachment process.

I agree you're not ready for after LRT. Be kind to yourself.

Lots of love.
