My parents are against me dating her but i think i love her what do i do?

i know it hurts that ur parents dont approve, but its ur life, u gotta make a choice, and then ask ur parents this question "did u marry each other because u u both were normal, or did u marry each other cuz u loved eachother?" and then say i will marry cuz of love, not cuz of normal ness, trust me, thell aprove right then..
