I don't know how typical it is, but I guess I'll give my experience and not try to use the 5 stages (of grief), but I will include the shit sandwich.
1) My situation is special and unique, of course the advice helps, but I need to take some exceptions because (cope). In this phase we are not ready to accept all the advice of people that have actually gone on the full ride. You have been served your shit sandwich. You believe your shit sandwich isn't as bad as others. It has lettuce and tomatoes and is served on artisan bread.
2) The worlds shittiest roller coaster/limbo. The motto here is "recovery is non-linear". You will feel things go forward and backward, progress is hard to come by, you are emotionally fatigued constantly. Hysterical bonding will happen here. You have maybe taken one big bite of the shit sandwich, and think you can handle it. But each bite is worse than the last. How big is this sandwich anyway?
3) The breaking point. You realize the shitty roller coaster ride is something you need off of. You take some *decisive action* to change the course of R or choose to D. It is not until this point you can "let go of the outcome". You will have received the advice before but you will not have been able to understand or implement it. This is a good time to revisit the advice you thought didn't apply to your "special and unique" situation. Your shit sandwich isn't finished yet, but you recognize that it's pretty much the same as everyone else's. You understand what is left, and have a plan to get through it.
4) PLOF. No more hysterical bonding. After having executed the change at the breaking point, you leave the constant emotional effort behind. This relative emotional calm gives you more time to think about what has happened. You can intellectually bask in the unfairness of the affair. You can bring it up to your WS, and they will support you in your feelings, but like, it isn't going to fix it. You are full but there are just a couple bites left on your plate. You are kinda pushing them around and not quite finishing.
5) R forever. This phase might not be forever. I am only ~5 years in and probably only 3 years past the PLOF. Here you are happy in life and generally satisfied with your relationship. You understand that your marriage is likely not permanent because you made peace with that at the breaking point. You know what you need, what you will and won't tolerate. There is still some effort, but the A is not a common conversation anymore. It doesn't consume your free time and thoughts anymore. You trust (2.0, not naive dumb trust that you will never have again) your partner and believe them to be a safe parter. Congratulations, you have eaten the shit sandwich. But you are sure you won't eat another.
