Everyone sees us as a happy couple, and I believed it too. Even after seeing a photo of my husband walking arm in arm with another woman into a hotel, I could not believe he was cheating—until he admitted it. He begs me to forgive him and promises to do anything, but I feel nothing except cold resentment. If I suffered, he has to suffer too. I keep him inside, edge him to his absolute limit, ignore every apology, and make him ejaculate repeatedly until my anger is finally spent.
