Glad they're addressing things, painful as they are, and Clark's point with the golden cracks was a very good comparison.
I do disagree with the need of feeling like one 'deserves' forgiveness though because technically if one does something wrong one deserves a punishment, which is why forgiveness is such a big amazing thing.
However, I understand the problem of Lois dwelling so much on her not deserving to be happy.

Hopefully she can learn to simply enjoy life again and take hold of their second chance.
