I've tried

Honestly, I dont even know wat really happened. When i think about it, all i remember is that i tried and i tried really hard.. But u didnt seem happy anymore.. 
No matter how hard i tried.. So i called it quits.. All i have ever wanted is ur mesmerizing smile lighting up my life. And i was just not able to feel that.. 

Sorry, if ever i have hurt you.. But the only thing that i wish for now is ur happiness.. If ever you realize that ur happiness is with me then ur always welcome.. I am and i will always be here for u.. But even if u happen to find it somewhere else, rest assured I'll be the happiest for u.. Love you..
