Here's an interesting article by Lori Gottlieb for The Atlantic about waiting for Mr. Right (and run the risk of him never showing up) or settling down with Mr. Good Enough:
Of course, we’d be loath to admit it in this day and age, but ask any soul-baring 40-year-old single heterosexual woman what she most longs for in life, and she probably won’t tell you it’s a better career or a smaller waistline or a bigger apartment. Most likely, she’ll say that what she really wants is a husband (and, by extension, a child). [...]
Oh, I know—I’m guessing there are single 30-year-old women reading this right now who will be writing letters to the editor to say that the women I know aren’t widely representative, that I’ve been co-opted by the cult of the feminist backlash, and basically, that I have no idea what I’m talking about. And all I can say is, if you say you’re not worried, either you’re in denial or you’re lying. In fact, take a good look in the mirror and try to convince yourself that you’re not worried, because you’ll see how silly your face looks when you’re being disingenuous.
Whether you acknowledge it or not, there’s good reason to worry. By the time 35th-birthday-brunch celebrations roll around for still-single women, serious, irreversible life issues masquerading as “jokes” creep into public conversation: Well, I don’t feel old, but my eggs sure do! or Maybe this year I’ll marry Todd. I’m not getting any younger! The birthday girl smiles a bit too widely as she delivers these lines, and everyone laughs a little too hard for a little too long, not because we find these sentiments funny, but because we’re awkwardly acknowledging how unfunny they are. At their core, they pose one of the most complicated, painful, and pervasive dilemmas many single women are forced to grapple with nowadays: Is it better to be alone, or to settle?
