Sounds to me like there’s an underlying issue the OP isn’t addressing.
She says that she and hubby are wealthy…I don’t think money is really the issue.
I think she sounds overwhelmed, and like she feels kinda put upon… and like her MIL’s actual kids are not chipping in with her care as much as they should be. And she might have a valid point.
I helped care for my FIL after my MIL passed unexpectedly. Luckily, all the kids chipped in and we even had adult grandkids in the rotation. There was enough help so that no one felt unrealistically burdened…we were really lucky.
I think the OP might be carrying more than her fair share, and maybe that’s what’s causing her to feel less than generous. Maybe she feels tapped out and like she’s already giving more than she can handle… and someone else needs to step up.
I stand by my statement that hubby should make the rules for his family…but I also think the OP has a right to voice that she needs help and can’t handle everything that’s fallen into her lap.
Something’s gotta give before this gets even more negative. Grief couples counseling would be a terrific idea for this couple. They’re both going through two very different things right now. He’s coping with the loss of his dad and worried about his mom. She’s had to live with an understandably depressed hubby and had to give a lot of her time to an understandably depressed MIL. She might be feeling resentful, and even guilty about feeling resentful…and kinda alone, and left with the work. She’s dealing with loss of freedom, responsibility that maybe should have fell more significantly to her children. It’s all hard. People do the best they can. Emotions happen. And they need to.
Death sucks and ruins everything. My hubby and I lost my dad and both his parents in the same 24 month time span. (and a 36 year old sister in law, and three grandparents…two years of hell) It’s awful. It’s easy to get stuck inside your head and stop communicating like you need to for a marriage to work.
I’m sticking by my original advice that the best solution is to let hubby make the rules for his family, and for you make the rules for yours.
But I’m going to add to that…you’re allowed to say so if you’re in over your head and you need help with care-taking. You’re allowed to say it’s not working and that there has to be a family meeting to figure out what to do. You’re allowed to talk to someone about how couples get through grief together, and the tough emotions that come with becoming caretakers for our parents and inlaws.
Anyway…I do wish you better times ahead. Time helps.
Be kind to each other. I matters now more than ever. If you can keep trying to be kind to each other…you’ll get through this.
