They live together but it's not a PA? Riiiiiiiight. Well, of course you know your father better than I, but just based on the above, I don't believe it.
It sounds like an odd situation. He says that he moved in with her while she was living with her boyfriend. Eventually her and the BF broke up and it was just her and my father living there.
It is possible that there is an element of PA but my father is 64 years old, diabetic and a heavy drinker and I'm pretty sure he has ED.
