Transcripts of interviews with six white British men were analyzed using interpretative phenomenological analysis. The current study aims to begin to address this omission by exploring the experiences of heterosexually divorced and separated UK gay fathers, focusing on their experiential journey from married, ostensibly heterosexual, men to living openly (more or less) as gay fathers. Furthermore, most research on this group, and on gay fathers more broadly, has been conducted in the US, with only a small handful of studies examining the experiences of gay fathers elsewhere. Since the 1990s most research on gay parenting has focused on intentional gay fathers – those parenting after coming out as gay – and the experiences of post-heterosexual divorce gay fathers (PHGF) have largely been overlooked, even though they remain the largest group of gay fathers. Before the so-called “gayby boom” in the 1990s the most common pathway to parenthood for gay men was heterosexual marriage.
