Re: Marriage of my choice
^ I agree with aahmed. My husband had the cajones to stand up to his parents and marry me, and they eventually came around (mostly).
Parents don't always know what is best for their children, sometimes they are blinded by culture, family pressue, and greed.
That said - if you can't stand up to them, and plan to live with them from the beginning of your marriage, do the girl a favor and tell her that you are a coward who can't speak up to your parents, and then get out of her life. Don't call, don't meet, don't e-mail her, just let her move on with her life.
Marry your cousin, treat her well, and pretend that you love her, even if you don't, and never mention this incident to her. If you decide to shortchange her by marrying her when you love someone else, at least have the decency not to let her know that she is second best.
