ok heres my two pennies worth.
I don't normally post on 'affair' threads as I never felt my H had an affair, he fucked around instead which I view as utterly different to an affair; IMO he was massaging his already disproportionately large ego by getting other women twat. He was abusive and wouldn't leave me, I was scared to leave him.
I suppose you could say I had an EA throughout all of this, with a man I always wanted to be with. He was married when I met him, I was single so I left well alone as 'I don't do married men' was my mantra as they could never be mine IYSWIM.
the OM admitted to me after I was married, when I questioned him if he had ever had an affair, that he thought about it years ago as there was a woman he was in love with but he left it alone; he then told me that the woman was me.
For the rest of my marriage until my H died I remained faithful to him, yet in my head I still wanted to be with OM; we still saw each other from time to time in a work capacity and talked on the phone. He became a bit of a sounding board when things got rough with my H.
His children left home and he left his wife telling me that if I left my H, he would look after me. This I never did. I stuck out my awful marrige in a state of fear and then suddenly my H became sick and died.
I am now with OM and it is the only really good relationship I have ever had with a man other than my father and DS.
So, I don't regret having a life spanning EA
