Online dating

So I met this guy on a app and I'm 16 and he's 17 and lives 4 hours away. I really like him and he says he loves me and he says stuff like your an angel, I'd die for you and I need you here. My two friends both told me to go for it but one of my other friends told me to end it and that this isnt going to end well and she keeps sending me photos of online dating and it ending badly. But I think I love him is it bad to love someone you have never met.
