What's Your Opinion? I need a little help.

I just found out that my 15 year old step-daughter is seeing a guy that will be 21 in December. I like the kid, but seriously, what does he want with a 15 year old? Don't answer that- I already know. He already has a 1 year old daughter. I am totally against this, but I haven't overreacted yet. I told her he was too old for her and left it at that, but it's really eating at me today. We both thought he was 19 until last night, then we got to talking about birthdays, and come to find out, he's nearly 21. I'm torn. Either I tell her he's not allowed to come over anymore, and she sneaks behind my back and sees him anyway, or I let it continue, and it'll be over in a few months. Everyone here is open minded and pretty liberal, so I'm asking opinions. My first reaction is to tell him that he's a pedophile and I'll call the cops if he comes over anymore, but that's only going to cause problems. I really dont' know what to do.
