My wife’s mother is in her 60s and divorced, and has been seeing a man her age for around six years. While he is nice, he is often inappropriate with family members (with jokes and comments, sometimes sexual in nature), and is generally annoying and immature. He makes no secret of the fact that he follows “glamour models” on social media.
My wife’s siblings have given subtle hints that his jokes and comments are not welcome, whereas my wife and I are more tolerant of him, primarily because my mother-in-law is apparently happy with him, and he is the only person in her life. Five years ago, she relocated for work to a very small community four hours from us, and closer to his home.
