Forget it chicky.

"I feel like I don't know him anymore."

I try talking to him. All I get is a wave, or a head nod, then right back to whatever is occupying his time... I try texting him, no answer.
I text him on his birthday and he says thanks, I'm surprised you remembered. So I have a good memory... You are still my friend...

Wanna know what takes my mind off of him? And makes me feel better?

People say Forget it. Forget about him. He's nothing to you.
Do you know how hard it is to forget a friend whom you care so much about, had great times with, gives great hugs, and made you feel good when you felt down? Super hard.
