Does he do (or try to do) internet dating?
Father has never been loyal to Mom. She came from a very poor Polish family and married Father for the Green Card to the US.
We think he uses fake internet profiles to meet women. Mom told me he has a friend called Mike who likes young girls, but Father is in his 60s.
Does he live alone or I'd there someone else in the apartment?
He is by himself. He spends months in that apartment drinking by himself.
