It is HARD to maintain. Extremely hard. I wish I could tell you that it gets easier but it didn't in my sitch.
Taking your potential R out of the equation, did you feel that an IHS strengthens a person better than if one person moved out? I'm kind of in an IHS situation now, but I make myself as unavailable as I can. It's been torture, especially in the last 6 months and while I feel that my progress has been slower than I liked, I feel that the changes are taking on a more true and permanent form.I feel that it would be harder for me to backslide on those changes.
