Tldr: my mil has offered to look after my extremely challenging and disabled dad but I don't want her to as I don't want to feel indebted to her and am worried about what I (or through me my kids) will have to do to return the favour.
My dad has been disabled since he has had a stroke a while ago. He can't get up, walk or do anything else without help. We have employed a 24h nurse and other staff to help care for him at home. My parents stay abroad so this is thankfully just about affordable. My sister and me have spent several months over there as we feel we can't leave my mum to deal with this on her own. My sister is there currently and has been there for much longer than me as I have small children that I can't leave for too long.
After his stroke he was for quite a while in a hospital and hospice kind of place but there they heavily sedate him to make him more manageable. He was extremely unhappy and depressed there. He was basically a vegetable. So we brought him home.
The problem is that apart from the fact that managing his care is quite complicated and involved, my dad's behaviour has also been affected by his stroke. He has become extremely aggressive and is also violent at times (though he can't at the moment cause serious injury because of his disability and weakness). He keeps shouting at my mum and verbally abusing her as he wants her to send the carers away and care for him herself. This is impossible as my mum is in her 80s herself. We are now at a loss about what to do as my sister needs to leave soon. He can't stay at home with my mum as it's too stressful for her and once my sister leaves he will bully her into doing whatever he wants as my mum is incapable of setting boundaries. We can't really leave him alone at home with carers as there are too many things every day that need to be managed though this is my preferred solution. We don't want to put him back in any facility as that would be the end of any quality of life for him.
My mil has offered to look after my dad for at least a few months. She is a doctor herself, runs her own clinic and has looked after quite a few of her relatives. I mean her staff would care for my dad under her supervision. This is of course an incredibly generous offer and I am quite touched that she would do this. My sister wants to take her up on the offer and for my mum to come and live with me. .
I'm very willing for my mum to live with us and I think that dh might be willing to accept that though he'd probably prefer not to. But I an dead against my dad going to my mil. It's too much to ask from someone and I would feel obligated and indebted for the rest of my life. I don't want that. My mil is quite an amazing person in many ways but she is also extremely dominating and can be very ruthless and manipulative to get what she wants. And she always wants something. She keeps involving herself in dh's life and our kids' life and it makes me very uncomfortable. She has form in alienating her nieces from their parents (as she believes that her sibling didn't parent them well) and I worry she will do the same with us as she seems to be a bit obsessed with my DD. Anyway, on the face of it we have got a decent relationship but I am wary of her. I'm always happy to help her and my dh' family in practical ways but I don't want to give her more power over me and my kids.
My sister is saying that I don't have to feel obligated and she will tell mil that the favour is all on her and I've got nothing to do with it. But things don't work that way do they? Of course I will have to appreciate such a massive favour and of course it will indebt me. Dh and me have also got serious problems so this added complication doesn't help.
I don't know what to do. I feel so guilty either way. Surely I can't sacrifice my dad (and my mum) for what might just be my pride? Or my insecurity? Or just because I don't want it? Or don't want the inconvenience of being grateful to someone?
What would you do?
