Congratulations, that's fantastic news!!! It's completely understandable that you're having trust issues, and you are well within your rights to expect to be able to discuss the events of the last half year. I would make it clear to your W that in order to reconcile you're going to need to have some deep, meaningful discussions on that. See if you can locate a good action-oriented counselor to help with it. Your W shouldn't have any expectations that she can just jump back into your life like nothing ever happened. Now is the time to set some boundaries. Good luck!
