Your wife's caving... let her cave, but do NOT PURSUE her... maintain that you and your son want and deserve respect and running out on them is NOT the way to show that... etc...

Whatever you are saying man its working.. if she wants to HOLD off the DIVORCE you AGREE...

Don't be NICE about it.. just say OK and exit the convo... SHE is having doubts and wants to stall... GOOD! That's what you wanted right was more TIME to BUST the affair right?

SHe has just GIVEN that to you.. take it, but don't do any happy dances in front of her... act like an adult.. ALWAYS do and show the maturest behaviour you can summon up... she will look like a child in comparison
