Yep, one way or another, if enforced, boundaries do work. Sunny, for you, they are working because you are truly in a place to enforce them REGARDLESS of which way they push your H. Many are not ready and attempt to set boundaries anyway ... setting themselves back when they are then unable to enforce them.
My two cents ... Peace PEI
