Why cant you forgive me?

Out of all the times i helped you,you treat me like this.
I was a best Friend to you , and yet you forget all our good times.
When you needed a friend i was there.
when you needed money for lunch i lend it to you.
Every time you fell i picked you up,just why cant you forgive me?
Being friends doesn't mean I'm at your house all the time. It means at least a hi and by. But i cant even get that.
You were my BEST friend and i was yours but all the sudden you treat me like i was a stranger.
Every time i tried to talk to you , you blew me off.
But now what?
