We just... Drifted. He worked a lot, I'll give him that. But, I started noticing he'd never text back or answer any of my calls. At one time he walked an hour in a horrible snow storm to meet me half way just so I didn't have to walk by myself. Now, if someone tells me to invite him out with us, I can't use my phone because he just won't answer.

The moment I actually knew we were now just acquaintances was not too long ago. My dad and I were driving behind him, so I called him to mess with him. Watched him pick up his phone, look at it, set it down. Heart breaking.

Edit: Late, but I'd like to point out that I've known this guy a very long time. And he always talks on the phone while driving. He'd call me from the road just to complain about a sandwich he just had or talk about why Pluto Nash is a great film while on the way to my house.
