ok guys. I called h at work at very db-like told him that it wasn't acceptable for him to just be away for the whole night and not let me know beforehand.

I get an email response from him that he will be gone ALL NIGHT tomorrow.

It's like he's acting like he has a "free pass" because I know about the affair now (he got caught) and that he told me "I don't love you anymore".

Please, please, please advise.
