Wow. Okay. I guess I do need a primer on what constitutes a boundary. I thought I was following exactly what was prescribed in the boundaries section of this website, but apparently I drastically misunderstood it.
Given the situation, can someone explain what I should have done-- or can yet do-- to address and set this same boundary effectively? If I've failed to do it here, then obviously it will come up again, so a different conversation will be required.
And, more than that, I absolutely MUST be prepared to respond to her proposed weekend camping trip (which would happen the week of April 10). I need to be able to set that boundary in rock-hard granite, and if I'm doing it wrong, then I very much need to know how to do it right.
