Ummm, I'm not sure what state you are in, but in some states guys over 19 can't date a girl under age. That 52 year old guy, is going to use her. There is a reason he wants her to abort the baby and marry him.HE HAS ULTERIOR MOTIVES!! A 17 year old won't realize anything except that she's in love and that he made her feel special. Ask him why would he even consider posing as her, if he knows that her real father will support any decision she makes on behalf of that baby. I can see right through this because I had the same thing happen to me somewhat. She's going to do what she wants but it's you that has to stop him doing whatever he wants with your daughter. Tell as many people as you can so they can be looking out for her too. This may help. I just know there is something that you can do, you don't have to take this
