Thanks everyone. I am not in a good place right now because as I mentioned I had a long holiday / went travelling and it's only in those circumstances where I am not obsessively working that I allow myself to think about these things. It tends to hit me in a way where I feel frozen and can't get out of bed or think or do anything and it's a big fear for me for that to take over. At the worst of it, I spent probably a year in that state and wasn't able to work or sort out the necessary obligations of life and so on, and I never want to get into that state again.
Just to clarify a few things - we aren't married. We weren't living together at the time of the A.
I was away at the time and oblivious to what was going on
Due to circumstances he and her were put together 24/7 for a long period
She was available and giving him lots of attention
I can't read minds, but after years of discussion, analysing, reading their messages it looks to be a situation where they became best buddies of some sort, which led to sex and then this went on for months back and forth.
Months of him saying "this has to stop" and then just doing it again (he can't explain). Her wanting a relationship / him to leave me and him refusing. In the end she phoned me and told me what was going on in the hope that this would get rid of me as she felt they should be together.
Even writing that feels like the worst cliche.
When I say it was 18 months of prolonged torture, I didn't mean that the sexual affair continued - it didn't - what I mean to be more specific is that while I was trying to recover and get safe again, he repeatedly betrayed me over and over with actions like meeting her because she said she needed closure or sending messages and so on. It was just awful and I was in so much shock and trauma that I honestly don't recall being even capable of processing what was going on.
The hard part is this: It was obvious that despite denying it, he really missed her and struggled to let go of the relationship which I have found impossible to live with. The best I can describe it is that he behaved like a crazed addict. We hadn't been together long, didn't live together, and with hindsight I have no idea why he didn't just go be with her if he had such a compulsion.
He claims he never wanted to be with her. He claims he always loved me and always told her that (she confirmed this to me directly so I know he's being honest). But I have never been able to understand why if you love one woman you would behave like that with another. It took in total probably 18 months for him to completely pull his head out of his arse and truly get the horror of it all.
Since then, it's been three and a half years and he's behaved like the model partner. He's blatantly obviously devoted, he clearly loves me deeply and this is a really steadfast thing that I am certain of - but his previous behavior makes absolutely no sense to me. He feels disgust when he thinks of her.
The fact it makes no sense makes it hard to shut down in my head. I have left for prolonged periods of time. I have, in fairness, put him through hell (not deliberately but because I was in so much pain) and he has never wavered at all. He will just wait, work at it, do whatever is needed because he says he loves me and always has.
His only explanation for it all was circumstances, and that he was temporarily insane and couldn't see what he was doing. He genuinely seems to have no idea. He maintains he never had romantic feelings for her.
The whole thing makes no sense after all these years, but there is always these nagging questions.
If he loved me, why would he do that?
If he loved me, why did he find it so hard to stop speaking to her?
If he loved me, why did he repeatedly risk our relationship just to speak to someone he said he had no feelings for?
If he loved me, why did he put my wellbeing in such jeopardy?
He is a different person now. i can't really explain that, but he can't bear me being in even the mildest discomfort for even a minute. He works hard every day, reliably and is always there no matter what. When he looked at me, his eyes light up. I see in front of me a man deeply in love.
So it remains, that I am baffled and confused over how and why any of this happened and I know deep down I will never have the answers.
I have resisted counselling I suppose because I don't see how a counsellor can ever provide me with the answers I need, and I realise nobody can.
