Marriage at 18!!

i am from bihar and where i live girls are usually married at the age of twenty or twenty one and some even at seventeen or eighteen but i want to build my career and become independent i want to build my own house and stand on my own feet my parents think early marriage is best for a girl and even my relatives believe the same i am only in eleventh grade and they have already started bringing marriage proposals for me which really worries me when i see other women here who are not married even in their mid twenties i wonder what advice you would give me i also feel that many families here are very misogynistic they believe women should only cook and clean and even if a husband is harassing his wife she should continue staying in that toxic marriage they say that some things are not meant to be changed but i believe divorce exists for a reason!!!
