Why won't he accept my help?

I am a 20 year old college student dating a 20 year old Moroccan man... we are so in love and enjoy being around each other when we are allowed to, and he dotes on me and always offers to give me things, which is all fine and well, but when it comes to me offering to help him or give him something he refuses. Says he doesn't like people helping him or giving him things... We are supposed to get married soon (hopefully) and he has a big issue with what others think. We are getting married cause we love each other and everyone else thinks its so he can have a green card and that severely bothers him. (Does this mean he really loves me or cares to much bout others or what?) Basically why can't he accept help and why does he care so much bout others opinion? need more info let me know.
