I don't believe it affects it. They "feel" divorced in cases where there is no legal action, and don't cycle back until those feelings fade. Unless the LBS moves on and is not open to reconciliation after divorce, I think there would still be a desire for the MLCer to cycle back once the crisis is over and reclaim their life. I am going through the legal portion, have been for over a year, and it has made no difference. He still continues to be weird and make weird contact when he feels like it, and when we've seen each other he is still clearly in crisis but very much not detached from me. I actually think it's better that we've gone through this part, as it creates a bit of a clean slate, and any marriage from here forward would absolutely be "new".
Don'tGiveUp's divorced friend just remarried his wife after 5 years of MLC, Charlyne and Bob from Rejoice Ministries were divorced before reuniting and beginning their marriage ministry, and I know there are several other great stories on the forum link Albatross posted.
