20 years...

I'm 18. 19 next month... I met this guy & he's 39. He's basically any girls dream guy. He's a gentleman, funny, protects me, showers me with gifts ; ect... We haven't even had sex. Even when I tell him I don't want the gifts, He insists that take them because he refuses to take them back from me.

I Really like him & he says he loves me but this age difference is just too big... What should I do ?
