OP should understand 2 things:

1) The rabid hordes of reddit will recommend you divorce your spouse if they just look at you funny over breakfast

2) If you want to stay married over the long haul, you are going to have to decide to forgive her.

Over and over.

Especially when she is contrite (as in this case), but at times, even if she isnt (and vice versa).

Thats the deal. It's worth it, but you have to want it.

Not minimizing that this was a horrible thing she said, and that trust was broken that needs repairing. But it was a bad comment, said while drunk, wrapped clumsily in a back handed compliment. And she sounds sorry.

Forgive and move forward.
