I met a white man at a gathering of people from my wife's nation in a city in the US. He had dated a woman from that country for about a decade, long distance. He met her parents, thought about proposing, but did not do it. Then he was in grad school, in a jury, working full time and was so busy he did not keep up with her and she married someone else. So he was pining over this woman, heartbroken. He was hoping to find a single woman from my wife's people. he had recently heard the Gospel. We encouraged him to get baptized, which he did, and tried to encourage him not to covet this other man's wife. My wife even showed him relatives pictures on Facebook to set him up. He felt it was creepy to marry a woman more than 10 years younger. He looked young, and I tried to talk him out of his hang-up. Women in my wife's country generally get married by 30.
Getting hung up on an old girlfriend or boyfriend is a big problem for some people. I believe it's coveteousness in a lot of cases. I also know a man who must be around 60 now who, as far as I know, has never married. He had a great job, got a doctorate, inherited a company from his dad, is a worship leader at church, had an outgoing personality. I can't really tell much about looks, but my guess is he would have been considered a catch, but his high school sweet heart broke up with him and married someone else. I guess that was it for him. I did not hear him say anything about wanting the old girlfriend. Maybe he settled on being single. But I thought at one point he might have ended up with the Nigerian girl from our church. In her kitchen preparing a meal before a Bible study, he asked her, "If you were olive oil, would you be extra virgin or dark and fruity? She said 'Extra virgin.' That's the cleverest way I ever heard that question asked." If I hadn't already gotten to know my then-future wife I might have borrowed that line.
