<human>: Can you give me the gist of the text in a nutshell?

Ill make this short. I turn 21 in 3 hours and my GF of 2 years is getting a limo and invited 2 of my friends and 5 of hers. She know's i don't like her friends and i don't like clubs. She is taking me to a casino/club and she know's 100% i don't want to goto a club. When we get there, I want to gamble and go out to dinner but im sure she will insist we go to the club because her friends will want to. Is it wrong of me to not goto the club? I just want to relax and she know's all of this..I am dreading my 21st BDAY. 

Sorry for the quick post..i am leaving any minute now. 

P.S My friend has my back on this and will be able to give me a ride if things go south. My GF doesn't know i know and thinks it's still a surprise.
<bot>: GF taking me somewhere i don't want to go on my birthday with her friends i don't like. She knows this. Is it wrong of me to not want to go?
