He doesn't see his kid

I started talking to this guy. He's 26 and has a son. He claims his ex doesn't let him see him, that's what they ALL say! I don't know if I can continue to talk to him because.. if you have a child you go to the end of the earth to see them. He could easily go to court and get joint custody or something! Seems like all guys excuse is, "oh well she doesn't let me see them" idk..

What are your opinions about it? Am I wrong for wanting to not talk to him?

He said he moved to another state so it won't be easy to see him. Right there's a red flag.. right? Or am I reading too much into it?
