I don't wanna be with him

Okay so I know you guys might think I'm an asshole but I don't want to be with this guy I've been dating for about a month anymore , he's
Really sweet and treats me nice but he's not the most attractive.  He's very faithful (at least I hope) and he's always there when I need him
. But I say again , he's not the most attractive person . I wanna end it with him because I honestly know I can do better . I want better for myself . But idk how to end it and if I really wanna risk hurting his feelings . Please help me .
