There's been a lot of emotion expressed in this reply.

If the two of you are unhappy enough that the marriage must end, let it be so.

Say that the marriage is dead and leave mention of others out of it.

Anger, spite, score-settling and all other hurtful things are best buried under the first tears.

The quicker you are healed, the sooner you can be in a healthy relationship.

There is no good way to end a marriage.

Try the least bad.
