When I walked in on my girlfriend screwing another guy, I never would have thought I'd be sitting at their wedding less than six months later. But who am I to turn down a night of free food, booze and pretty bridesmaids?

But at the back of the room, at the rejects table, I'm captivated by the woman sitting next to me. She's gorgeous and smart, and I can't work out how she's single. Until I realise she's the groom's ex.

This single mother and I are about to turn this wedding into a night our cheating exes will never forget.
