The other common mistake newly-bombed LBSs (usually LBHs) make is that they want to take any spin, spew or even truth from their wayward spouse into account, wrap it up with all of their own guilt, and then IMMEDIATELY set about to trying to "fix" the broken marriage.
IT DOESN'T WORK WHEN THEY ARE WAYWARD.
It takes PATIENCE, to continue to learn and grow and work on your own GAL, 180s and doing what you can to attract them back . . . knowing that you will have PLENTY (weeks, months, YEARS even) of time later, during the PIECING phase, to show her how you've changed.
You try and do it now, and it's going to come across as weakness and supplication, and that AIN'T attractive to her, and it'll kill YOUR self-esteem.
