Debs - thanks for starting this thread - and thanks to others for their wise contributions. It came at a good time for me, as I've been having a wobble. I am now 9 months on from discovery.
My DH gave her up instantly and there has been no contact between them whatsoever, after the initial few days, when she texted, 'phoned and E mailed him at work like a woman possessed. He was very clear he wanted no more contact from her - and she hasn't - directly. What she did was post a load of bile about us as a whole family on various social networking sites, including a vicious attack on our 11 year old DD, whom she had never met, but perceived her to be a "Daddy's girl" - and therefore a threat. By the time she did this, my DH had already realised how awful she was, but that was the final nail in her particular coffin. He absolutely detests her now, so I have never had any real fears that it would start up again - and I genuinely don't think he would do this with anyone else.
By and large, he has been brilliant. He went for individual counselling and that helped enormously. He is the most attentive, adoring husband anyone could wish for and he still cries that he nearly lost me.
The wobble this past week came when we were discussing why she thought he was only here for the children - it was pretty evident from things she said and an E mail I saw that this was her view of things. Yet he is adamant (and always has been) that he never told her this. However, like most people in affairs, he was pretty manipulative, and in response to her questions about whether he would ever leave me, replied "No, but in any case I could never leave my kids". Finally, she asked him whether he would leave me even if there were no kids, to which he replied "No". This made her very angry. He accepts now (and this has been hard for him) that it suited his purpose for her to believe that the kids were the stumbling block and he hates that (took me ages to get him to acknowledge this too). After many long conversations about this (his denial was really angering me) this week, we are both feeling a bit battered and bruised.
For the most part, I know we have an amazing relationship now and I have got past the low esteem issues that blighted me in those gut-wrenching early days. I have never had a shock like it in all my life and would say unhesitatingly that moving on has been the hardest thing I have ever had to do. And I know I'm not there yet. I read on one of the many sites I devoured in the early days that it takes 2 years to come through an experience like this.
We had been together for 24 years when this happened and it seemed to come out of the blue. Last year was the worst of my life and the way my DH dealt with his guilt was to treat me and the DCs (2) appallingly. He lost his temper all of the time, made cutting remarks, was withdrawing from family life and generally being a pain to live with. The affair wasn't the only thing I had to forgive - and he understands that only too well.
I have always understood how these things start and I think there ought to be a public health warning about how some people are vulnerable when they feel that they aren't achieving at work, are not attractive any more etc. My DH was too proud to own up to how unhappy he felt at work and although he didn't work with OW, he used to. She got back in touch, kept telling him how wonderful he was (in her memory) and of course it reminded him of a time when he was happy at work, confident in his looks and professional life and the rest is history.
Some of you might enjoy the twist in the tale though. After repeated refusals to meet her, he finally relented and the first meeting took place. It turned out, she had put on about 4 stone in weight and he remembers feeling crestfallen when he saw her. The sex was pretty dreadful too - so much so it didn't happen again for a few months, but by this time, he was addicted to the whole secrecy/texting thing and it was much more about the "it" than "her" iyswim. The next time she suggested meeting, he turned her down because at that point, he just wanted it to be all over with her, but lacked the courage to deal the final blow. He had also come to see her volatility and bunny boiler tendencies at that stage and thought that there might be a terrible backlash.
In my more insane moments, I have even felt sorry for him that he has gone through all this grief for what was crap sex with an unattractive woman - does that sound weird?
So, I know now that I am not "there" yet. I love him deeply and I know he loves me just as much. I am getting happy moments back and I know I'm better than I was. But it is still so hard some days - like an obsession really and I know I'm not really "well" because I still have fantasies about revenge (on OW) and regret being so bloody dignified.
