I contacted MOW before I found SI.
I had a three hour coffee with her.
She said things that verified what my H told me was true. She also said a lot of things that I will never forget such as "You have to stop thinking about me in bed with your husband". and "if there was nothing wrong with your marriage, he wouldn't have been with me". She said much more but I was in a daze and can't remember.
Would I do it again? No.
Please listen to the wisdom in these replies.
She will tell you what makes HER feel better, whether it helps you or not. She will also lie, without a doubt.
She told me things that almost made me give up on reconciliation. If anything influences you one way or the other, let it NOT be her.
