I Can't Decide! >

Hi, I'm an Indian living in America, and I need advice with what I should do after I turn 18. I'm almost 17, and I'm stressing because my parents talk about my marriage, an arranged marriage I am supposed to agree to. I don't know how to say no because I know that if I did, my parents would destroy me mentally. They are not bad people, I assure you, they've been very nice to me recently and I think it's because they want me to agree, and I know they want what's best for me, but that comes second to their reputation. My parents will definetley chose a guy at least 7 years older than me, very very very conservative, lives with parents, and exactly like my parents, putting his reputation first. If I agree to the marraige then I'll have to live a normal house wife life, with not a lot of freedom. But that's the exact opposite of what I want to be. I'm very well educated, I go to a prestigious high school and I'm going to major in coroporate law (I hope), I'm also very modernized. I don't like all the restrictions put on women in my culture, in fact I deteste half the stuff my culture has.
There's one other factor. I have a boyfriend, and we've been happily together for more than a year now. The thing is, my parents will never agree to him because he's not Indian (not even near India), they don't even know I'm dating, because if they did, I would've been married by now.
I want my kids to grow up to love whoever they want, and not ever have to stress so much like I have, but I just don't know what to do. If I leave, they'll force my younger sister to get married, and if I don't, I just don't know what to do. Please help! :(
