the marriage was already on the brink of being declared 'over'?
background:
both parties worn down over the years by being in volatile marriage with numerous issues.
both parties agree to separation. have had many temporary separations in past. got back together each time for sake of ds1 and 2. both feel marriage is over.
BUT a week before partner X decides to instigate the final separation, partner Y unexpectedly meets someone else.
partner Y has been loyal person for 20 yrs and was only receptive to meeting this new person as they craved affection due to the state of their marriage.
SO... given that the person was only ever on the scene for such short time, is it kinder to keep quiet about it? or is honesty always the best policy?
