"I believe my husband when he said he didn't have an affair to cause intentional harm. After the affair was revealed, I asked him if he had considered my feelings, and he said "You weren't relevant to my thoughts."

I think this is true. At least it was in my case. I didn't consider my wife's feelings either.

What we think or what we know or what we believe is, in the end, of little consequence. The only consequence is what we do. ~ John Ruskin
