Gonna. I'm sorry, but it still sounds as though you are speculating about how he feels (and felt) rather than KNOWING it. I honestly believe that for a couple to heal from this, there needs to be a shared understanding. For us, this has been an ongoing process.
I would never have expected myself to heal if I'd ever thought that my husband was still pining over what might have been and was staying with me out of a sense of duty. I know myself pretty well and like I said before, it wouldn't even have occurred to me that I could have got past this, had I felt that way. This is what I meant about you having set yourself an impossible task and I still think you have wholly unrealistic expectations of yourself.
It is however possible to love - and not punish - while you are building the shared understanding of what happened here. Our story over the past year has been about that long process to build our shared understanding. But throughout it, we have loved each other very well indeed.
It would be a mistake to think that it's only you who needs understanding. If you are to go forward as a couple or as two individuals, it is crucial that you BOTH understand. Perhaps most tellingly, it has been important for my husband's mental health that HE understood the what and the why. And it certainly has been for mine. In fact, I was talking to DH last night about your situation and he thinks this is what is missing for you. You don't have a shared understanding.
This process is long and fraught with setbacks - but I honestly don't think anyone gets over this without it. What we both believed about this a year ago is very, very different to what we believe now.
People in affairs have the most enormous capacity to delude themselves and I'm afraid that doesn't stop when the affair is over. For example, my husband had deluded himself (at the time and at points since) that this affair was about sex. It would have been very comforting to me perhaps at the time to believe that, but of course the facts didn't add up.
I know him pretty well (we've been together 25 years!) and I knew he was telling the truth about the poor quality of sex with OW. In this sense, the facts added up. If he'd ever thought it was even good, he would not have turned down OW's repeated appeals to meet more frequently and 2 months would not have elapsed before he met her again. But of course what didn't add up was: if it had been about sex and that was bad, what on earth sustained it? This is of course how we arrived at our shared understanding that this was never just about sex - he had other needs.
This is just an example (there were so many others, I could write a book!) of how my understanding differed from his. I couldn't move on at points because the facts (and his actions) during the affair just didn't seem to mirror what he said he was feeling at the time. I used to get so frustrated and angry that he couldn't see what seemed bloody obvious to me, about a whole host of issues. In one memorable conversation, I said "If it looks like a banana, tastes like a banana and you told someone else it WAS a banana, chances are, it IS a banana"!!!
More times than I can tell you about, I felt like giving up. I used to feel drained by this process, but I knew I had to do it, otherwise I'd never be able to move on. Fortunately, my H felt the same.
Equally, I have had to compromise on my long-held beliefs too. As an example, one of my sticking points until relatively recently was that he CANNOT have loved me during the affair. He knows with certainty that he never stopped loving me, but accepts that at that point, he didn't love me enough. I know in reality that in terms of his feelings for me, he wasn't running on empty during the affair, because there were glimpses of care, desire and pride in me. We have therefore settled (in terms of our shared understanding) that just as there have been times when I haven't loved him enough over the past 25 years, this was true of his feelings for me then.
It took infinite patience and many tears to build this shared understanding - and I'd still say that on some things, we are a work in progress, but we love each other so much and so deeply, it has surely been worth it.
I do believe that every experience teaches us something. My worst case scenario would have been that neither of us really learned much about ourselves as a couple or as individuals. Had I given him his marching orders on discovery day, I would never have learned what I know know and of course, neither would he.
The point is, are you and he up for this? Do you both have the stomach and courage to go through this process? I fear that if you don't - and I'm afraid it still doesn't sound to me as though your H is brave enough - you will not heal as a person and the marriage will never reach its potential, with the real risk that something else could happen again.
