should i leave?

i think we're getting far. you don't fight for me like u always did. and i don't really fight for u like yesterday. we're far... we're same... and we can't be like we should be as a couple for 4 years. we just waste our time. i don't know why we should be this stupid. but i think this relationship take us to the wrong place. our relationship take us to be worse. i don't like it. i want to enjoy my life with laugh, happiness, sadness. i want to share everything but not like this. everyday we just be a good couple for a moment. and after that we mad each other. why?
