well, from my own bad experiences of what happens when pushing for commitment too early.. i'd say dont push it :-/
Most of the more successful recoveries I've read, happened when the leaving spouse comes back, and says, "I'm ready to commit". It usually doesnt work too well, to goad/badger them into it.
Even when you want to take a foam bat and whack them repeatedly until they come to their senses.. i'm just POSITIVE that would help... wouldnt it?
My current status: june 2006. Wife ran out and filed D. Finalized Jan 11, 2010, after 12.5 years M. 3 wonderful sons caught in the middle
