Agreeing with you in that in a WAW situation, WAW will usually withdraw more when you do "nice" or "positive" guestures.
I wish it wasn't this way. Is there anything else you can do other than a 180 in this case to regroup yourself?
Perhaps non-verbal communication, or how you spend your time may let them look at it in a different light?
The reality appears that we 180 to protect ourself, perhaps Affair Burst, but rely on LUCK that the spouse would like to come back home and take responsibility for what they have done and show a renewed committment.
