I Ask You,male Or Female What Would You Do If

OK, so I used to be on EP and I met some interesting people there. There was this guy and we became friends. Platonic, if that is possible. Of course there were some playful innuendos. After EP, we stayed in contact. He shared LOTS of personal information, so he was easy to find (stalk). Most of what he says are true, except I have uncovered some serious untruths. His age, marital status, children, ex, that's all true. Some things he has said about them are not, they are things that can't be undone. Now, he is supposedly in the hospital, ICU. Yet, he has made comments on his facebook page, so I know he is lying. Is he catfishing? He doesn't ask for anything. We've had a lot of fun talking about all kinds of things, not just personal things. I really don't want to stop talking to him, but I really want some ideas on some things I can do to kind of let him know that I know that he is pulling my string. Kind of call his bluff. Any ideas?
