Jumping in on a couple of the topics here. First, some pages back, Acorn contributed regarding, among other things, the importance of healthy detachment. I cannot stress enough how essential that was for me. I remember reading various books and blogs and hearing about how the MLCer's actions aren't directed at the LBS; it's not personal; I needed to learn to not base my own happiness on the outcome of her crisis. And at the time, that was absolutely unfathomable to me. How could it possibly not be personal - it was the worst and most personal betrayal; it destroyed the very foundation of my life. And yet... as I started to work through it, I realized that that was my codependency talking. I had (and still have) an identity that is separate from and not reliant on my spouse or my marriage. My value and my path to peace and contentment and joy were mine alone to determine. And yes, I even came to accept that her crisis wasn't about me - it was about her own pain and past trauma and her attempt to find happiness via distractions and external validation and the dopamine rush of the new and exciting. And, as others have said... even if we forgive and reconcile and truly do move past the impact that BD had, it's impossible to forget it. BD was a traumatic event in our lives, and even though it hopefully doesn't define us, trauma does contribute to the shape and path of our lives.
An at-home wallower might resolve their crisis without leaving or divorcing, and maybe even without a physical affair... but I have a hard time seeing how they work through it and figure it out without at least an emotional affair. It might not even have a strongly romantic bent to it - but I think that for them to resolve it, they have to have the realization that the problem wasn't the marriage or the home life, but rather, was an internal problem within themselves. They can do that by leaving home, changing jobs, getting a new partner, or some combination of those things, perhaps. I feel like with wallowers it probably takes longer to resolve things, in general, because the high-energy MLCers can reach rock bottom pretty quickly while wallowers can just be stuck for long periods of time - even more so if they're still in their homes. I'm not saying that resolution without an affair and without leaving home is common, just that I do think it's possible. My W lived elsewhere for 7 months in 2020-early 2021, but she was in our home for several hours, 5-6 days a week, during that time. She had an emotional affair but no physical affair, and we never legally separated. It all played out over a shorter timeline than many of the stories here, and I don't know how much the pandemic affected the course of her crisis. But she moved back home in April 2021, and refers to her MLC as a time when she "doesn't even know who [she] was."
I'm not sure what that adds to the discussion; I'm from 2020 rather than 2017, and I've gone from posting at least daily (and visiting several times a day) to often going several months between visits and rarely posting on my own thread anymore. The main reason is just that there's not much new to say... we're just living our lives. It's not perfect; there was no earth-shattering revelation when we reconciled. We just mutually decided that we wanted to be each other's person again/still, and we are doing our best to do just that. We're wiser and a little scarred from our experiences, but we appreciate our relationship more because of that, I think.
