In what country do you live? In the USA nobody, including parents can force you to marry someone if you don't want to. From your post I assume this must be some kind of arranged marriage because you stated "when I saw her I don't get any feelings for her".
The bottom line is it is your right to decide whom you marry, hence the final decision is ultimately yours. Speak with your parents and tell them you do not wish to marry this woman and would they rather you be happily married for years to come or divorced after only a few months because they took your decision away from you.
