“I don’t know if it’s a good thing,” she says. “This whole thing is
muddled; you know that. I don’t need to explain it to you. But I can
absolutely see why you’re hesitant to tell Ryle. Knowing his ex-wife is
sharing a bed with that block of perfection has to be extremely
emasculating.”
I raise a brow. “Not as emasculating as beating your wife should feel.” I’m
a little shocked when the words come out of my mouth, but I can’t take them
back. I don’t think I need to, though, because luckily, my best friend isn’t a
ride-or-die sister.
Rather than be offended, Allysa agrees with a nod. “Touché, Lily.
Touché.”
