Getting married or not

My fiancé and I got engaged 4 months ago.  He is very adamant on getting married as soon as possible. I do want to get married too, but one part of me sais I should wait till i finish college. My family also wants me to wait till I graduate, and I know I would let them down if I got married now. They are very traditional and culture is very important for me and my family. This is creating an issue between my fiancé and I cause I know that it hurts him. I feel that whatever i choose I'm loosing. What do you guys think is the best i could do? What would you do? I know that I want to marry him for sure, he is the love of my life, i just don't know if I should wait or not. I am here for unbiased opinions. For those married, did your relationship change?
