I'm casually seeing a man who is seperated from his wife for 6 months, they don't live together?

So I've been going to his house but never staying overnight my choice not his. The only time he contacts me is to hookup which I'm fine with, we hooked up once years ago before he got married so it's not like I don't know him. He says some strange things and I'm thinking he's seeing me as an emotional crutch, someone to validate him once in a while. he says he'd love to tell people he's having sex with me and take a picture of us together but I'm not comfortable with anyone knowing esp not the woman he's seperated from due to the fact they are not divorced. it might just be silly pillow talk I don't know, do guys normally talk that way?
