EU Bookray: The Rosie Project by Graeme Simsion
Interestingly enough: https://www.gatesnotes.com/---/The-Rosie-Project
Don Tillman, professor of genetics and most likely "suffering" from a form of Asperger's, is convinced that his social awkwardness and small number of friends indicates that he is menat to remain alone. Yet he must concede to the statistical probability that there is someone for everyone, and he embarks upon The Wife Project. In the orderly, evidence-based manner with which he approaches all things, Don sets out to find the perfect partner. She will be punctual and logical—most definitely not a barmaid, a smoker, a drinker, or a late-arriver.
Guess what happens ;)
