She is 98. Was in assisted living, but broke her hip after two months. Had surgery, but refused to do rehab. Now is in nursing home. Can't walk. Not happy. Has some dementia. No real health problems. Does not want to participate in activities. He thinks he has to go every day to see her. This has been going on for two years now. I go with him more often than I want to. He has high blood pressure and I can't make him see that this does not help him. We have been married 50 years and could be enjoying our retirement if not for this.
Clearly you'd like to get away, so do it! Enjoy yourself while you have the chance.
