JKS,

My 2 cents is that it doesn't matter why the WAS comes back -- as long as they agree to "no contact" with OW and give you full visibility.

Pretend he comes back because someone bet him $10 that he wouldn't -- that's a crappy reason right? From my perspective, who cares? You now have a starting line and an opportunity. If you can be a spouse that only a fool would leave, keep up your 180's and meet each others needs, then in 12 months WHY the WAS came back won't matter at all -- you'll have the marriage you want and that's what matters.
