She can’t have been that tied to the kitchen sink if she managed to have an affair. depends. If most of the communication was online and the affair was emotional for the most part then it’s possible.
I had an affair. My ex was controlling to the point he had prevented me from going back to work, moved me away from all support, hacked into my social media, turned off the heating in the garage so he could be sure I couldn’t have it on during the day while he was out. Insisting we should have sex after the birth of DC and refusing to take no for an answer.
Ironically it was the fact he’d hacked into my social media and me realising that led to me getting chatting to someone else. I changed all my passwords and ended up talking to someone on there a lot. We started an emotional affair and managed to meet up once. Then eXH found out but by then I had already decided I was leaving. I had tried to on numerous occasions but it just wasn’t possible with no work, living miles away from any support and with children to look after.
But I knew that if I’d stayed the control would have become that much tighter than it already was.
I absolutely regret the affair and can hand on heart say that I would never do it again. But sometimes abuse creeps up on you and something makes you realise that it’s happening.
Nobody else is to blame for my affair, I am, but equally it’s naive to think that the cheated on partner is always a helpless victim who had no part in treating their partner in such a way that they ended up meeting someone else.
And I would bet money that there are men in the same position, whether posters on here wish to acknowledge that or not.
While there definitely are people who cheat just because they can, affairs are almost never that black and white.
