Fleishman is in Trouble by Taffy Brodesser-Akner

This is a hilarious romp through Toby Fleishman’s life after his wife Rachel leaves him. Just as he’s getting used to his new singleness, fending off the women who are happy to hook up with him despite his short stature, Rachel leaves the children with him for a weekend and doesn’t come back. Toby is forced to adjust his life and his attitude. This is a very funny read with enough wisdom in it to keep it interesting.
