Help! How can I impress my rich white boyfriends family with my black self?they are very respected people.?

Well, I am very nervous to meet my boyfriend's parents! When we met he never told me he was rich. He is German and I am from a Caribbean Island, He was here with vacation when we met. We met at the club and he was drunk and I helped him get in his car and drove him home and then grabbed a bus and walked home. He really liked my kindness and the next day he called me and set up a date with me. And since then he has been so kind and sweet and bought me flowers everyday. Well his vacation ended one month later and he went back to Germany. One day when I came home from school he was there with flowers I was so happy because we talked on Skype and I seriously begin to like him. He said he was here for 1 month again just for me.

Well I didn't think much of money or anything, While he was here I let him meet ALL of my ghetto Family!! (my aunt that wears a night gown all day long with no bra, my crazy grandpa who screamed at us for coming unannounced, my 16 year old pregnant cousin who flirted with him, my other aunt who stole some lamps in the house, my other uncle who told him he will only let him marry me if he has a nice penis like a black man etc. etc.) so embarrassing!!!

And when I told him I was saving up to buy a ticket there because he was coming here but I want to meet his parents, He says: Here is a ticket to Berlin, just hands it over! I was amazed! and then I asked him for his address so I can see his house on Google Maps. Then we saw this gigantic house with this gigantic pool All in this MOFOKA's yard!!! And a trampoline TOO! with 4 cars! Hot-damn! G-us!!! And now I have a ticket to Berlin for the 29th of June and I'm so nervous to meet his parents Because I know I'm loud and sadly,I know some may consider me ghetto. I talked to his parent already and these niggle's can't speak English! and I can't speak Germs! I thought I can impress them using a lot of big words. But English is not my first language.

And to tell you the truth, while writing this I used Spell Check like 100 times!

Please help me impress my in-laws! Well I started doubting myself, because I thought I was classy but now I think I'm just another ghetto chick. I also thought I can impress them wearing a lot of jewelry and my diamond ring that he gave to me.

I'm sorry that this is long but I wanted to give you a lot of details so I can get good advice.

I love my boyfriend and I know for sure that he loves me because he treats me good, he talks to me about US and our future and he is not like disrespecting or whatever.
