Hope4us - I don't know anything about OW. He claims nothing happened and nothing ever would. Just that the fact that he could have feelings for another woman meant there was something very wrong with us. I am undecided in whether I believe anything happened between them. I don't think he would ever admit it.
JMHO but "know thine enemy". Find out what you can or can handle. Sometimes knowing something about the OP gives you a clue as to what is missing in your R. Like H4U says though, this is not for the faint of heart...it hurts like hell but for me its worth it.
If it is truly and EA only, you might want to read the book "Not Just Friends" it has a wealth of information and can give you insights and questions that you may not have thought of before.
