My uncle in law moved in with us, and we didn’t set ground rules... my wife spent 12 hours per day with him, and now we are getting divorced.
That’s too bad.
I would sure encourage you both to find a way to get back together. If that means letting her uncle go to a nursing home, then so be it.
Happens esp to parents of severely disabled kids/adults.
I chose to stay single for life due to my choice to be my sons medical careprovider 24/7.
No room for husband/wife relationship. Would not be fair to the man.
Have had male dogs (Labs) for 25 yrs. Love the Too Cool Cold Nose Crew and the solitude.
Sorry for your loss.
