Will it be easy for my husband to take care of his very selfish mom in our home?

I say since this happened give it a try and see where it goes. If he's leaving everything on u than u do what u feel is best for ur heart and soul. do u guys have children? is it just or was just the 2 of u? u didn't mention that.

I'm not saying what he did was very nice. It was awful. Once u get married u suppose to disguise things together. Maybe u guys should seek family or marriage therapy. Only u have to decide like everyone else making decisions u have to do the same. Pray and stay focus.

That is awful that he would try to make that kind of decision without your consent. My parents have tried to force moving in or us moving near them for awhile and it is always a hard no from me. I also already told my husband I would never live with his parents. I actually like his mom a lot but still a hard no.
I would put up a for sale sign in the yard and see what he thinks of that unilateral decision.

The question is not how easy /hard it will be for your husband, but what you will do. You are the only person you can control.

I advise you to work closely with a geriatric care specialist and have an assessment of your home done by a physical therapist. Follow their recommendations for any home remodeling or adaptive equipment that your MIL will need.

Then, work with a medical social worker to pull together lists of resources for everything from personal care assistants to home heath aides to meal delivery services.

I would include services for anything your husband typically does around the house: lawn service, car maintenance, basic handyman.

Plus, in the eventuality that you are recruited into care (and you WILL be recruited), you need services for house cleaning, laundry drop off, and child care.

Also, add to the list respite care for when your husband needs a break and a couple vacations, individual counseling for you and couples therapy for the two of you to save your marriage.

Good luck!
