Idk if he's involved but I wouldn't rule out a ons/hooker because during one of the last times we were together he called me by my full name. He never does that. It's always the short form of my name or just baby. He said it over and over. It bugged me. Either he was enjoying me because it had been mths since we did it last and he missed me or he was reassuring himself he was with his wife because of guilt.
Unfortunately, there is a third option. He was afraid he was going to call you by the wrong name by accident and overcompensated.
