I've read all of the other post, and yet i kinda understand what your going through(even though imma guy).
If you like that girl, don't ever let go of that relationship. If your parents disagrees with your decision, then say
"This is my life! Even if your my family, you don't always decide it yourselves! I've got to decide on my own whether which gender will i love and be with!"
That's what i thought tell me if this helps or not.
(And if you wanna change just ask me and i know how to change people if needed, it's not a business yet but i think i can do it.)
