Well, if you feel it best to step back, then I'd go with that gut instinct. Seems like you can only pound each other so much before tiring out/realizing the futility of trying to change each others' minds.
BTW, I think you know this, but I just wanted to clarify that I didn't mean anything sinister with my last couple of posts. I was just reflecting on the tenacity you two had. You guys must be part pit bull.
