One more thing just popped into my mind... when I called OW, H responded with a VERY forceful (read: unlike him) and VERY angry "the harassing phone calls and emails WILL stop."
One more reason to keep up the phone calls. It's definitely getting to him.
If your spouse is cheating on you and what you're doing is upsetting them... you're likely doing something right..
If your sopuse is cheating on you and what you're doing is putting a smile no their face, you are likley enabling them
It's definitely getting to him.
