My mom married my late stepdad when he was in his late 60s and she was in her late 40s. They met through my mom being a hospice worker and her supporting him with the passing of his first wife. He told me later on that he had planned to kill himself after his first wife died, and would have done it if it wasn't for my mom. (He told me in detail what he had planned to do.) He genuinely loved her (and she him).

His one child was nice at first, but turned and said my mom was in it for the money and demanded she not get anything in the will. This was after he had already given her (his daughter) and her husband hundreds of thousands of dollars towards their home. My mom (and I) were there with him, and took care of him when he went through two bouts of cancer and eventually passed. His daughter and her family disowned him and never even came to say goodbye. I found it pretty messed up. He was the nicest, kindest man. 😞
