Fast forward a few years and Jack’s attraction to Paula became much more obvious. Karaoke night at the Red Lion consisted of him abandoning me for a sing-song with angel-voiced Paula, culminating in ‘Hey Paula’. It was a great laugh to everyone, very funny, but I could almost see the sparks flicker between him and her. Every time he saw her he’d break into, ‘Hey, hey Paula!’

I finally flipped one Christmas Eve when he danced with her almost all night. He told me I was paranoid. He told me that I was imagining it. She was my sister. What did I think he was?

Janine and Freddy’s wedding is a surprise, though. Either that or I’d given up by then. I’d been fitted for my bridesmaid dress pre-baby, and although I’d regained my figure soon after having Charlie, my boobs were enormous and heavy with milk. The dress wasn’t made for breastfeeding and in the end I gave up and decided to go home.

I fully expected Jack to stay. There was rarely any point in trying to get him to come home with me; on reflection it was always an opportunity for him to meet new women when I wasn’t there. This night he came home. I can see why now. The pictures of Paula with the pussycat look are outside the church from a distance. Round the back. In the background I can see my father’s grave and bile rises.

I upload the photographs of Paula as a new thread on Monica’s Facebook. Straight away people are liking them and tagging them and sharing them and there’s a direct message. It’s a journalist from the Sun asking to meet Monica. Offering a substantial sum of money for her story.

I delete it. Now I’ve posted these final pictures I feel like I really am at the end of it. I’ve shown the world just how low he can go. Paula, ever-simpering and saintly, will be shown as she really is. A man-stealing bitch. There’s still a slight niggle as to why she hasn’t admitted it. Not that I’ve seen her since that wedding. She’s disappeared off the face of the earth. Shame, probably. Can’t face me. But she’ll have to one day.

I Google her and there are no results. An old Facebook page with her smiling out, last updated five years ago. Where is she?
