My good friend,~missing

Back in school,I befriend a guy
We motivate each other for our own success,
We have no intention to expand our friendship beyond "what it suppose to be"
But then he found his love interest
And things get worst when I feel like I'd lose my bestfriend
We fight,fight,fight non-stopably for nothing..
And we din take care of each other anymore..
All good things dat we've done together before,gone~nuthing left behind
We hurted each other for our own pride
And until today,we dun even dare to say hello to each other..
Why a good best friend has to be an enemy?
