Im losing all my friends and maybe my Family HELP?

[Sad Woman]

I met this guy (pretty nice guy) he is a friend of a goof friend mine, i donno how they met but oh well.. We start dating and i have to admit that he is a nice guy to go out with, funny also. but now is the dark side.. he comes from a family that i dont like at all. they live in a middleclass neiborhood and i just think I dont fit in that kind of live.. My mom has always told us not to have contact with ppl that doesnt have the same of highier income that we do because they are ignorants.
My friends also have been telling me to stop dating him because they re not going to be my friends anymore because im getting "dirty".
My mom just asking me to bring my "special" friend home to a dinner, (they want to meet him), but im afraid when she find out about he and his family how she is going to react.

Anyways at school my friends all the time make fun of me, and say that I need to improve my skills like a Maid..

WHAT IM GOING TO DO..
Im thinking to stop dating him because this is going to be a problem..

And im tired to being called maid.

I know he is nice.. but I know also that even i decided to still dating him he is not the right guy for me..

My Bestfriend told me that in this world are two kind of different ppl, they and us..
Im sad...
