If I Never Met You by Mhairi McFarlane

"When Laurie’s partner of eighteen years, Dan, dumps her to ‘find himself’ (and leave her on the shelf at 36), she is blindsided. But not as blindsided as when he announces that his new girlfriend is now pregnant. Working in the same office with Dan is soon unbearable - until the day she gets stuck in the lift with her handsome colleague Jamie. Jamie is looking for a way to improve his reputation in the company and what better way for Jamie to advance and Laurie to give the rumour mill something else to talk about than a fake relationship? As Laurie and Jamie progress from Instagram snaps to dates, dancing and more, Laurie feels herself falling further for her unlikely hero. But you can’t break your heart in a fake relationship. Can you?"--Publisher.
