Shocked, I searched for another post I once did in response to someone who had found their H engaging in a text relationship with another woman. Having re-read it, it doesn't entirely fit the bill here, but I just wanted to reiterate that it is terribly important for you both that you don't fall into what can be a very comfortable trap of concluding that since nothing actually happened, nothing would have happened.
I know it's different, but there were definite stages in the build-up to my H's affair and we have since discussed what he would have said if I had discovered what was going on at the various points. The stages were: friendly innocent E mails, friendly innocent texts, sexually explicit and loving texts prior to the first assignation. All of this was over a 12 month period, with a gap in the middle when she gave up trying to persuade him to meet her.
In the early stages, they had what could have looked like a very innocent exchange of E mails between two old colleagues who hadn't seen one another for years. Except this woman wasn't just an old colleague - she had tried unsuccessfully to get my H to have an affair with her 13 years previously - and he hadn't seen her since.
This time, she was married and purporting to be happily so. My H reckons that if I'd found out about this alone, he would have been embarrassed (that he hadn't mentioned it) but would have insisted that it was all very innocent - he says he even told himself this at the time.
What he wasn't acknowledging though was that he had started to look forward to the contact, especially when she filled her E mails with how wonderful he was in her memory.
The question he didn't - and wouldn't have asked himself was "what am I getting out of this and why am I doing this?"
We have agreed that had I found out that there was contact between them - at any of the different stages - my H would have tried to convince me (and himself) that this was just him being "a bit silly". Even if I'd come across one of the pre-assignation texts, my H would have told me (and himself!) that he never really would have gone through with it and would have come to his senses before actually doing anything.
The proof was in the pudding though. He didn't come to his senses at all and got immersed in a full-blown affair. I think it's telling that he didn't start to feel terrible guilt and stress until he couldn't "pretend" any more. It's amazing the bargains we all make with ourselves.
I don't think I'd have bought any of this for a second, but I shudder to imagine that I might have. I know we would have had the showdown from hell, but I might just have "bargained" with myself that a crisis had been averted and as long as he hadn't met her, it was all going to be fine in the long run. This just wouldn't have solved the problem though.
Your H might be comforting himself that he would never have gone through with any of this - the most important admission he can make to himself (and you) is that in all probability, he definitely would have met women for sex.
That's going to be a tough admission for both of you, but it's so necessary, Shocked. He might insist till he's blue in the face that he wouldn't have done this, but like I said before, he simply cannot know how addictive and pleasurable it would have been when he started receiving replies from women who were willing to meet him.
