"And like that, poof. He's gone."*
I am not a person who disappears. At least not deliberately. If I don't return a phone call quickly, I'll likely send an email letting you know I got your message and that I'll call when things slow down. If I don't want to talk to you because you've pissed me off in some way, I'll let you know. I won't just disappear.
I don't understand how someone can communicate with you on a daily basis and then drop off the face of the earth with no explanation, but I am faced with that situation right now. I alternate between being worried, sad, and furious, and I have no idea if it's something I did or said or if this person just doesn't have the emotional strength to communicate with me or anyone right now. No idea. And that's the part that pisses me off the most; I want to know why almost more than I want to get a response to my last email or phone call at this point.
But overall, I'm sad that I've lost a friend and I'll never know why.
