It suddenly occurred to me that no matter when his affair with Rachel had begun, she hadn’t been the cause of our breakup. Dex and I had split because we weren’t right for each other, and because of that fact, he had been able to fall in love with her. Had we been on solid ground, Dex wouldn’t have cheated on me. The realization was somehow freeing, and it enabled me to let go of another sliver of resentment toward both of them.
