I agree with, garry. If she filed for the divorce on grounds unrelated to infidelity, she can't hold the relationship you've developed since separation against you. You should bring that up in a calm conversation with her (Jm, she probably still wants the divorce, deep down, but didn't expect you to find someone else first/get over the separation so quickly). Given that she petitioned before Andrea was in the picture, I can't see what legal ground she'd have for holding things up...
