mkultra, H had affair with my friend, a woman I knew from my kids playgroup. Definately up there on the ICK factor. Disrespectful on both parties. I have especially dealt with HER blatant disregard for my marriage and my life, and squeezing her way in, even when she is married. And yep, kids are close with her kids. They talk about her kids all the time.
ICK to your H's blatant disregard and doing those things in front of your family. ICK ICK ICK
