My grandmas brother who was in his 70's was married, he had a side piece who was 40. He had to get his leg amputated below the knee from diabetes. He got the side piece to move in the house with him and his wife and got her a job getting paid as is care taker. All three came for thanksgiving that year, shit was awkward, don't how he made that work.
Extra note, when he was in the hospital about to get his leg amputated, he had about 6 women from different cities fighting to take care of him.
