Discovered he was married, he said she’s a stalker, what should I believe?

This guy introduced me to members of his family but I discovered recently a Facebook page indicating he’s married. He told me the girl is a stalker, his mom and everyone says they don’t know her. He says that he don’t want her and she’s mad about it. Today I did more digging and most of his family members including his daddy are Facebook friends with her. I’m confused…if this girl a stalker then why are your family friends with her on Facebook? He tells me he’s not married and don’t know her. Not sure what to believe
