So there you are, in Alaska, dumping frozen water from frozen buckets, and rueing the day you met the...albatross. Would you tell her she needs to leave in 60 or 90 days, and that until she leaves, she needs to follow your new rules or you'll have the sherrif remove her even sooner (and hope Alaska has no horse boarder eviction laws, lol, or that she never finds out what they are)? That way, you've got something of value that she wants (time to find a new place). That damoclean sword hanging over her head might help her behave. My main concern is not for her at all, so much as for her horse, but more so, for you. You're a decent person and you deserve to have your "boarder"(??) on a leash. I think you really need to white board this one, for the rest of the time she's there. She needs to know CLEARLY what she needs to get done. And if it's on a board, it can't be argued or denied or whined away.
