How did you break up?

Hi mylotters. i have been having relationship problem for the past 2 years. My parents totally disapprove of my relationship with my boyfriend from the very beginning. I am currently with my boyfriend for 6 years now. i'm thinking of breaking up with him for the past 2 years but because i cannot let go, we have been dragging it until now. i wanted to drag a little more until augest until after his birthday to tell him that i'm really over with it. But i'm now thinking if i should wait. We were very lovey dovey in the beginning but now, we can't even eat without quarrelling. have you broken up before and i would really hope to hear your experience so i can take in to consideration and any advice you have for me will be greatly appreciated.
