Sex and the City, Season 3 (2000)

Carrie:
[Narrating] Later that night, I got to thinking about men, and women and relationships. Or more to the point, how women feel men disappoint them in relationships. Then a radical, almost earth-shattering thought popped into my head. What if everything isn't the man's fault? After a certain age, and a certain number of relationships; if it still isn't working and the ex's seem to be moving on and we don't, perhaps the problem isn't the last boyfriend, or the one before him, or even the one before him! Could it be, that the problem isn't them, but horror of horrors - is it us?
