Dear old love: Effects of reflecting on nostalgic memories about ex‐partners on current romantic relationship

Research on the impact of ex-romantic partners on current romantic relationships is mainly focused on negative aspects. Here instead we focus on the potential positive influence of reflecting on nostalgic memories of one's ex-partner. In three studies, we found that reflecting on nostalgic memories of one's ex-partner increased the perception of current relationship quality (Studies 1- 3) and approach motivation towards the current relationship (Study 3), compared to a control condition. We also tested a potential underlying mechanism-perception of self-growth. We found that perception of self-growth mediated the positive effects of reflecting on nostalgic memories about an ex-partner on perceived current relationship quality (Studies 2 and 3) and approach motivation in the current relationship (Study 3). Implications for research and therapy are discussed.
