Monica’s problem is that she would rather be single than to settle for any man who would actually want her, a problem she shares with a lot of women who see their status determined by the status of their husband or boyfriend.
There would have been men willing to date her - just not rich and powerful men.
Does she own a mirror? It was odd that President Clinton was attracted to her, though I imagine that was more for convenience than attractiveness, but she was 22 at the time, not 39 with a bad reputation. It would be like me, 52 and overweight with health issues, imagining that Sofía Vergara was in my league, if I were single.
