what do you do if a guy from when you were 12 had found you and he's married and he tells you that he's going to leave his wife?

I have a friend that this is happening to her and she's in love with him. He telling her that he loves her and that he can't leave his wife tell his baby is born. That way she has insurance. But she can stay on medical even if she's not with her husband, it's better for her if she's not marred. My friend is having doubts about this guy. She way going to go meet with him in three weeks but she's not sure that she's going to do that.
