I'm really glad that the anger has come through SC, even if it gives way to sadness. You know at least that it will come again.
What comes through so vividly from what you write is your sense of utter bewilderment. You must be wondering whether you have been living in a parallel universe for the past few years, because you don't recognise any of your H's post-affair rationalisations. It is revisionist bollocks indeed...

It seems to me what you need most, is to make sense of what has happened. This is why infidelity and the associated deceit tend to make a relationship break down worse - because it messes with your mind. People often torture themselves with fears that if they missed the signs, what else in life has been happening, that they have been unaware of? Is anything as it seems? It's as though the whole world order has changed - and only you were unaware of it.
When a relationship ends because of unhappiness in one or both of the partners, both of them are sighted on the issues. In fact, I have never known a relationship break down through "natural causes" - and it was a shock to the people involved. That decision has usually been made after months or years of trying to resolve differences, especially where children are involved.
Whereas with infidelity, usually one partner has been pretending that all is well with the marriage and the true compartmentalisers in fact often display no signs at all. This sounds like it was for you, SC - there were no signs that he was unhappy, he certainly didn't tell you that he was - and all this is an enormous shock.
Have you ever challenged any of this with him? If he is sticking to the frankly ludicrous notion that he would have left anyway - and the OW is incidental to the fact, why did he not speak to you about his misgivings before embarking on his affair?
I suspect he won't be able to answer that, because his version of events just isn't true. The unhappiness in your marriage, I suspect was caused by the affair - and not the other way around.
In your situation too where there is a double betrayal, I often wonder why one or both of them didn't press the brakes at any of the numerous steps on the lead-up to the affair. I find this fascinating.
My female friends and I have often talked about how eachother's partners are so completely off-limits, that to even consider a sexual relationship with them would feel like incest. I genuinely think you've got to be a particularly abusive sort of person, to cause this kind of hurt. I think Dittany is absolutely right in this case therefore, but I also think the OW is abusive here.
Therefore I wanted to ask you, looking back, did either of them display any abusive behaviours? Did you notice or experience any cruelty, but bargained it away? The book Dittany suggests would be an interesting read, to see whether your H and friend were emotionally abusive in their relationships.
I think it might be a good time to see a counsellor again, but choose carefully, because like I often say, there are so many myths about affairs, some of them peddled by counsellors too, I'm afraid. I do think you need some objective sense brought to bear, because your H is so locked in this false script, it won't come from him.
Keep posting and keep writing SC. These are still very early days and I suspect the shock still hasn't quite worn off.
