The comments were in no way meant to belittle standing, and I 100 percent agree with you that not everyone here is dealing with the same thing.
In real life, I know of two cases where the person came home; one was a man and one was a woman. Both were relatively self aware and actively seeking therapy/spiritual guidance, although they did move out and have affairs. Their spouses did a lot of things this site recommends, like stay busy, draw boundaries, and in one case even began dating or considering dating. However, neither person was doing things like wild spending, truly bizarre affair partner, radical personality change, striking change in habits etc. that are regularly reported on these forums.
What I see on this forum, unfortunately, is no attempt to distinguish who might have a crisis and who might have a serious illness. In fact, people who suggest the latter are routinely and categorically shut down or told to go elsewhere, despite the fact that many of the symptoms they report are in fact the norm among posters. (Many of us are aware of a poster who attempted to alert people about frontotemporal lobe disorder who was repeatedly shut down, even when she made sure to qualify her remarks.) The truth is, early bvFTD is often mistaken as a midlife crisis. This is uncontroversial; you will find it in serious articles about the disease.
Until there is a way to truly expand the thinking of the forum that YES, some people are arriving here with very sick spouses, etc., it is in my opinion irresponsible to use language that could put someone or their children in harm's way.
