It just confirms what type of a person she is - the nerve of her to rub it in your face. Try not to react any further to it. She is not worth your time. Be the better person. Perhaps keep a copy of the email just in case H brings it up and doesn't believe you. But try to put it out of your mind.
If H does contact you about your message, try to remain calm. Do not badmouth OW to him because it will reflect badly on you. Just tell him you do not want her to contact you ever again and leave it at that. You have every right to be angry but don't come across to H that way.

As far as H's SIL goes, be careful what you say to her because it may get back to H through his brother. I am pretty close to my H's SIL and we've supported each other over the years. But with your D being final, she may find herself in a tough place. It was nice that she called you and mentioned some things or do you think she was fishing?
