Makes you feel better and also validates his leaving...
Let him SQUIRM... Honestly, exposing his affair and inviting him to work on the marriage is a powerful hit on him... It will terrorize him for months...
Serving him with D papers right now accomplishes nothing.
And yes he is a coward.. all cheating people, particularly the OP who hides in shadows and attacks your home covertly are cowardly beyond belief. I particularly criticize the OP... they are homewreckers... They are no better than an arsonist setting fire to your home while you sleep... They belong in jail.
That won't help you at all. SO why do it?
Just go live a healthy life for yourself.. that's the best medicine for you right now.
