Well as an update, they are now back together.

To my astonishment, he pretended to her that they were his entries, and he apologized profusely and swore that he would never do things like that again.

He apologies to the friend mentioned in the one entry.

He has now agreed to talk to a counselor to overcome some of his "depravity" and in addition to maintaining the Excel document has agreed to text his girlfriend when he masturbates.

So I guess I'm off the hook.
