OP... alas, it's not going to teach anybody anything. This thread is really only for you. The next potential affair partner who may be lurking will be unaffected by what you have posted because there really haven't been any consequences other than the fact that you're feeling sad that it's over.
I think the 'we' and 'us' is very telling because that is your perception of your relationship as it was... and nobody is going to persuade you otherwise on that because it's part of the reason that the affair happened and continued for the time it did. To remove those terms of 'togetherness' would invalidate it, wouldn't it? I don't think you're ready for that yet, to have your affair (which meant a lot to you), dissembled into stark little bits of not-much-at-all.
I'm sorry for you because I think there is still a strong delusion and a little bit of the 'if only the stars would have aligned' in your posts. I also think that you're very readily accepting the flaming because to do so, prevents worse, more vitriolic flaming, and this enables you to continue posting about this man and the relationship you had. You're entitled to do that, of course, this board is for everybody but I think that a period of introspection - as well as venting as a salve for you - would be helpful.
Affairs are not ok. They're really not. No excuses, not ever. It won't stop people having them but they should own their behaviour more honestly.
... and if you REALLY want to make this a cautionary tale then post about how you felt in your darkest moments of rejection, realisation that the man you loved (and you do) was never going to be with you, the excuses you made for that and the lies you told to yourself that he felt the same, the fact that you have no control over your feelings for him, for the clock you can't turn back with a 'reset', can't ever restore his feelings for you to a time before the affair when they were genuine and harmless... post about that and it will be worth reading. People will identify with that pain, will understand better perhaps, and, if anything was ever going to dissuade somebody from an affair, those would be the words to make them think about it very, very seriously whilst they still have control.
