Well similar to what I said to SteveLW in OB's thread regarding boundaries around a PA, I'll preface my answer with "you never truly know how you'll respond until you're tested in real life", but honestly believe I would not and could not accept her back at this point. Too much damage has been done. Lies, betrayal...etc. I honestly don't feel a desire to be with for her anymore, but still lament the impact to my family situation. It's a odd paradox. Mad at the forced change in situation paired with the knowledge that even so there's no going back.
Fair enough BL. It's interesting that although there is no going back you still want her her and OM to fall apart. I am not saying you are wrong for having these feelings it just runs into the whole forgiveness and unconditional love conversations.
