Antonio,

First thing....Slow down and breathe.....

You didn't cause this, and you can't fix this

Secondly...Don't try to mind read what he is doing or not doing. How he feels or doesn't feel, because you really don't know how this is affecting him.

Thirdly.....Just ignore the email. There is nothing good that can happen , for either of you, by responding to it.

For now, get some rest, try to relax , and breathe....
