I think MN has quite old fashioned view points on affairs and women that stay. It's sad and I agree with other posters that it's really NOT the place for support.
Affairs are not a marriage problem they're a cheat problem. I'm not saying the marriage may or may not have had problems but affairs are a cheat problem. That's clear in a lot of literature on affairs nowadays. Victim blaming is never cool.
I read a lot on here about women who stay, commentary tends to refer to a woman usually of a generation above who stayed and has been bitter etc etc. Again things have moved on. Rugsweeping was common place. It’s very different now, anyone involved in true reconciliation knows that you can not expect to just lock trauma away.
We're more aware. Affair psychology has moved on. We don’t put up and shut up anymore.
Healthy reconciliation now means facing a number of key truths head on. It's not pleasant and hardly for the faint of heart. Discussing issues of trauma, PTSD, right to informed sexual consent (which was taken by the cheat) has to happen. The cheat needs to feel remorseful and work to be a safe partner. Tbh if the cheat isn't working their absolute arse off any one advising the betrayed would say leave.
Women who stay are not 'dumb' and don't 'lack self esteem' far from it. They chose to stay for a myriad of reasons. Belief their husband could be better, belief that they are happier with than without, belief that they can work through all the nuances and tricky questions the affair raised and heal, understanding that they still love him and even a careful appraisal of who the cheat was prior to the affair. Ultimately it’s a belief people can do wrong and grow and change.
Choosing to stay is hard. It is hard because it goes against what society believes is healthy for the betrayed partner.
That’s what sucks. It is NOT their shame to carry, it’s the cheat’s.
As for the AP, hating them is common, it’s part of the trauma response, you work towards indifference. In the case of married men, broken women who fall for married men will always exist, they aren’t special just wrong time, wrong place. They cause a huge amount of pain, their choice, they assist the husband in taking the right to informed sexual consent, they often dig knives in post affair, their choice but ultimately he let someone like that into the families lives. The cheat and betrayed partner have to own that truth, the walls of the marriage would never have crumbled of the cheat hadn’t let the AP in.
Staying is not for everyone, but I loathe the blanket opinion of reconciled wives on here. It isn’t helpful and doesn’t assist in (predominantly) women on here getting the right AND SAFE advice to stay if they wish and heal. Which is why I also always advise people to go to other forums like surviving infidelity.
Affairs pass pain on, broken meets broken and they pass pain from the cheat and AP to the betrayed. Pain that is indescribable to anyone who has not experienced it. The important thing is that the pain is stopped at some point and healed. Whether that is staying or going. No one should be mocked or ridiculed for their choice. The important thing is that all parties heal and learn from it.
