Eric, it is possible to show love (NOT pursuit) with actions as well as detach. For me, it is showing forgiveness and treating them like a human being even though their actions feel like a slap in the face. It is about not getting involved in her drama for your sanity and not letting her actions and words control you.
For me, it is being pleasant and light in our interactions but not "chasing" and trying to keep my focus off my H.
