I would encourage you not to think in absolutes through this. Continue to "give grace" toward your wife (while holding firm on your boundaries), and leave at least a little side window to your heart open to her. Even 20% of divorced couples remarry, nearly always reporting that the new marriage is way better than it was before.
By remaining forgiving and civil (again, while holding firm to your boundaries and protecting your family), you keep a future option open . . . for YOU.
