Its worse than you think - you don't want to know the FULL truth, trust me. Emotional affair...haaaa right, you don't want to know.

Push the pedal on the gas as hard as you can - expedite the divorce process

Play sad, moping around - kinda pathetic and accommodating, otherwise she'll sense a dirty fight coming. Negotiate with her on the divorce , based on whats best for the kids (sad but its a great emotional tool, not saying you don't believe that but they don't obviously and if used correctly you ll get the agreement - based on whats best for the kids.

Once shes done getting pumped and dumped and CHAD leaves her (which they always do - about 90 days in or so...) she will need a source of supply and that going to be YOU and making your life miserable and dragging the divorce out. PLaying victim to support her narrative that she just slipped and fell on CHads cock instead of respecting her marriage, husband and family unit.

DO it while shes focused on the new relationship emotional HIGH, be smart and diligent playing fox and outsmarting her, I did 95% of the negotiating for my divorce via text, or phone call - preferrable text. after that, she doesn't deserve SHIT from you nor your eye contact

OTHER TIPS:

If you have kids, negotiate at least one of them for tax write offs - pays more, they don't know that $4500 or so

Have your phone recorder ready incase they start acting crazy

Do not, and I repeat do not negotiate on where she can live county etc. anything outside of the current county you live in. Keep her close
