Wait to see if the mediator can reach an agreement between the 2 of you before telling your L to take a hike. If mediation reaches an agreement, you can still ask your L to review it, but be wary as he may suggest you to not accept the mediated settlement so as to stuff his coffer in L to L negotiations or the very expensive in court dance.
Just so you know, my W asked for another chance right before the D was final. She never showed any sort of sign that she would be strong enough to rebuild so I told her NO before she could get to begging. Over a year later I dont regret my decision.
It sounds like you are done also with your W. Move forward and dont let her wishy washy emotions distract you.
