He says he's born in 1996 but his passport says 1998. He knew this and failed to say anything before it was official because he "didn't feel like it." I just wanted to know his ACTUAL age because I'm not KNOWINGLY LYING on our son's birth certificate!

Now he's threatening me, I'm scared, and I don't know what to do...

(P.S. We are in America. Me, born and raised. Him, from Ghana.)
