Can i just married him because he is a good muslim ?

Assalamu aleykum I met this guy 3 years ago despite the fact i do things to make him upset, and i don't understand why i do that , he still like me the way i am and want us to get married. Most of the time i think i'm not good enough for him .One thing i love about him is the fact that he is a good muslim , his honesty and loyalty and i don't know what else i like about him, apart from religion... my parents like him i'm still confused about my feelings for him and i'm scared of losing a good man any advices will be greatly appreciated.
