Can't tally love: Tracking favors may hurt relationship, research indicates‎

They say that love is a two-way street, but that may only hold true to a point. It turns out that couples who obsess over equal give-and-take may be sabotaging their relationship, suggests a study involving University of Toronto Mississauga researchers. The findings are contained in a Personality and Social Psychology Bulletin paper authored by Impett, former UTM graduate student Haeyoung Gideon Park and two other researchers from the University of Alberta and the University of Michigan.
