I'm not sure what to do or how to feel about this.
My grandpa has been near death for several weeks now. His second wife, with whom he has been for 20 years (they met shortly after my grandma died), is not exactly the most congenial person. She can be downright nasty at times. My grandpa has had dementia for years, and she gets really frustrated with him and yells at him when he obviously doesn't know what's going on. She's been his primary caregiver for as long as he's had dementia (probably about 10 years now), and it's clear that the stress is too much for her at times. She's not always like that, though. She can be quite caring with him at times. She was crying by his bedside and was clearly really upset about losing him when I visited on the weekend.
My grandpa has been in the hospital for over a week now, and we've all been visiting with him. My step-grandma goes in every day to see him. Yesterday, my aunt happened to be there at the same time as my step-grandma and she witnessed some pretty awful behaviour. My step-grandma was getting really rough with my grandpa (he's on narcotics, he's confused, he's weak, and he sleeps most of the time). At one point she actually ripped the blankets off my grandpa for no reason, and he asked her to stop.
Then my aunt phoned my step-grandma later in the day just to check in. She asked if my grandpa had eaten supper and my step-grandma snapped at her to stop asking questions. She then said she didn't care anymore. This isn't the first time her behaviour has caused a rift in the family. When my aunt told my mom about everything that happened yesterday, that was it. She was understandably furious. I'm furious.
The thing is, I've gotten closer to her in the last few months. I know she appreciates when I visit with her. I don't hate her, and I think a lot of her meanness can be attributed to stress. That doesn't excuse her behaviour, but it does explain some of it.
I can't imagine my mom or her siblings having anything to do with my step-grandma once my grandpa passes. I'm afraid I'll be asked to make that choice too. I feel sorry for her - she's lonely, stressed and exhausted. I'm extremely angry with her for how she's acted, but I don't know if I'm prepared to cut her off. I'm going to feel bad no matter what I choose to do.
I guess what I'm asking is, is it normal to feel conflicted in a situation like this? I feel like a bad granddaughter for still having compassion for her. How would you feel in this situation?
TL;DR: My grandpa is dying and my step-grandma can be quite mean at times. Should I cut ties with her once he passes?
