What should I do about this man?

This is a rather long story soo I will try to make it quick. I hooked up with this guy at concert and stayed with him at his friends house, simple enough right…wrong! Turns out the guy I hooked up with was 25 and has a kid. I had originally told him I was 19 but I have now told him that I am really 17 and still at school. But even now he is still in contact with me, and is always calling me and attempting to come to my house but since I still live at home until I go to university that would not be wise. So I have no idea what to do, I really like this guy but us being together could affect his future (he is a Solicitor), and his rights to see his son. he doesn’t seem to mind that I am very young but when I told him well he was rather hysterical. But the truth is we haven’t had sex, but yet he still keeps in contact and understands my boundaries. Soo the question is simple what should I do in this situation? It has been 2 months and I still don’t what we are, is this a relationship? A chase? Or one big game? please Please PLEASE HELP ME, no one I know can help me thank you :)
