Thanks for the reassurance. It makes it a little easier to tolerate. He knows he's suppose to respond. It's like one long text chat. I post, he responds. He's missed a day here and there before but not this long.

This is all I came up with to tell him. What do you think?
"I feel like you bailed on me. I know your probably busy or something but this sucks. You usually write back by now."
