How do I tell my best friend – someone who was always against anyone going near her twin brother – that I’ve not only been sneaking around with him since we were eighteen, but that we were also in a relationship and months from being a family of three, all while keeping it a secret from her? That we split up because he thought I cheated just weeks after losing our daughter? That we’d steered clear for two years but broke the dam by fucking each other’s brain out yet again?
