native - I think you found 1 answer & didn't realize it. Again, your W got too close to you & thus pulled some sh*t, to back off again. Not knowing what she wants or how to act. It is good she owned up to her actions though.
Dating, take a hard look before going that route, as far as divorce is concerned ... do you want that possibly used against you?
