Thanks so much.
My mom can get around well but uses a walker. That's part of the issue of my place, several floors up/ one bedroom and one bath. If an emergency happened that would be a big problem with her trying to get out. We've had a few emergencies at my place, thankfully she hasn't been here during all those emergencies accept for once when it was false alarm. All the other times she was with me, I haven't had to evacuate.
She actually had a boyfriend at one point who visited her at my sister's a few times. It was good to know she had a companion. She doesn't need a nurse any longer though. She is at my sister's as a permanent residence as part of the plan after healing from her injury.
Just to be clear, mum has stayed at my place many times. She knows my place is smaller. We're actually closer emotionally than she and my sister. At this point though, my mom does not like the going back and forth between my place and my sister's. It's almost an hour an a half away. She likes being in one place and each time i ask her about coming to my place, she says how much she loves me but she prefers staying put rather than all the back and forth. Before her health issue though, my mom and sister were very distant due to my sister's temper and other personality issues. However, she and her husband have a spacious place which is a blessing. I still will try to get a larger spot once I can afford to. As of immediately though, I cannot.
The only discord is between myself and my sister, not my mom. There are some other things to explore as I've found through our county's department of aging and social services. My life coach and mentor have both told me that I should hold firmer boundaries with this situation because my sister is rude and it doesn't make sense (to mentor and coach) for mom to be going back and forth when the house is fitting. I sleep on the floor when mom is with me.
