I'm a L and I don't know what the he11 you are talking about. Forgiveness is not illegal or against your legal interests.
It's also nothing you need to share with her now.
Condonation is when a couple reconciles after an A, and later the LBSer files for D and uses the earlier A as the reason, (although there was no repeat of the A.)
That is not "forgiveness".
I was told by a lawyer and paralegal that I should probably stay away from talk of forgiveness until my wife and I had come to a separation agreement, I'm assuming because I would not be able to perhaps use evidence of an affair as any sort of bargaining chip, or be able to threaten a lawsuit, if I had said I had forgiven her. I would never forgive OM, though, of course, unless I just needed to, to let it go.
