I'm writing to offer a slightly different perspective on why pick-me fails.
I think - that is, believe - the BS's recovery demands taking responsibility for oneself.
IOW, to recover from infidelity, the BS needs to find value in themself, and needs to interact with reality with eyes - all the senses and all the brainpower - as wide open as possible. The BS needs to realize they have to be their own prize.
It follows - for me - as night follows day and day follows night that a healing BS knows their WS hurt them, and they need to develop self-love. In reality, the WS is dangerous to the BS. And what healthy person wants to increase the danger in their life?
I guess R may be possible if the BS does not love themself, but I don't see that BS building a great M, and IIRC, I didn't want to R unless I saw a great M in my future. (Of course, I can't say what I'd have done if I hadn't seen a great M in my future, and my great M may not be anybody else's.)
IMO, d-day presents BS and WS with opportunities to take themselves apart and put themselves back together with more strength, more ability to love, more lovability, and less garbage baggage then before d-day. Seizing that opportunity makes the best of the sitch whether the partners D or R.
The pick-me dance is an attempt to hold onto an M that did not serve the BS well. In essence, the pick-me dance says the BS needs the old M. The BS who does pick-me dance sells themself out, which is the opposite of taking responsibility for themself.
Success after being betrayed is not D, and it's not R. It's finding joy again and leading a happy, productive, satisfying life.

For the record, the WS is in even more need of taking themself apart and putting themself back together.
