Definitely know she won't change, I've accepted that fact. And I wish I could minimize contact. I will likely become her main caretaker in the next year or two, though. She is getting more and more frail, but doesn't have the funds for an assisted living facility. She had two falls recently because she rarely uses her walker in her apartment, so she lost her balance and went down. Dunno how I will keep my sanity, but I'll figure it out when it happens! I guess if I think of it as more of a professional relationship rather than a personal one, it may work out.
Thanks for all the support, everyone! She went home today (yea, later than initially anticipated, oye!). Took a 'brain break' day and just enjoyed the simple things.
