@nikita871,
I hate to advise you against a happy, fulfilling life, but if you plan to continue to live where you are, you must follow your parents' direction, or you risk being murdered.
The headstrong choice to risk your life for a teenaged boyfriend is not a choice you have the maturity to make at your tender age.
I would hate for your life to be ended in this way.
I personally wish you would very carefully try to escape to a place where you can truly live a fulfilling life and make choices based on what's right for you, but the odds of a young woman making that transition without being victimized, I think, are too small.
