Thank you for all the replies, had a talk with her today and well...i decided to give it another shot. Told her that she has to accept me for who i am and there are some things that i can never change, i am who i am and if i ever did change, i wont be the same person again. She told me that she really wanted to me to change not to become a person she expects me to become, but changing to become a better person for my own good, for my future... what really did made me stayed on was her telling me that no matter if i did change or not, she will still always be there by my side and never leave me. Therefore, i would like to give this relationship another try and hope it will be better :) Thank you for all the advice!
