This is simply the lonley old man myth again. Yet another feminine social convention.
This notion is one of the biggest AFC rationale ever perpetrated on men. Is lonelines a disease that necessitates a cure? If men could be made to believe so, think of the potential profit to be made from, and the potential for manipulation of, men. The real test for a man is how he lives with himself, alone. Precious few men ever truly allow themselves to be alone and learn real independence and self-reliance. The vast majority of guys (particularly in western culture) tend to transition from mother to wife with little or no intermission between, going from LTR to LTR until they 'settle' without ever having learned how to interact as an adult.
The fear of loneliness is entirely too exaggerated in modern western romaticism. The popularized fear-mythology of becoming the "lonely old man who never loved" is the new 'old maid' myth made popular in an era when a woman's worth was dependent upon her marital status and equally as false a premise. But in our brave new generation AFC, men (who've become women) are repackaged and shamed into believing this horsesh!t as part & parcel of this feminized gender role reversal. And thus we get Speed Dating and eHarmony and a host of other "conveniences" to pacify the insecurities that this reversal makes poor fatherless boys believe we 'should' have as part of ourselves by no other virtue than that we were born male.
Don't buy into the powder-puff idea that if you don't find your ONE by the time you're 30 and ASAP you'll tempt fate and risk a life of quiet desperation. This contrivance only serves the interests of women who's imperative it is to enjoy their party years in their 20's with as many Jerks as they can attract and have a stable Nice Guy who's petrified he'll live a life of loneliness and desperation waiting for them at 28-30 to marry and ensure their long term security.
Don't buy this lie. The man who is comfortable with himself and confident in his true independence is the one that women will want to be associated with and to share in it. How you handle being alone and what you do with that freedom is the real measure of a man.
If you're single and 50 you STILL have options if you're only brave enough to explore them. I know divorced men in their 50s who're dating mid to late 30s women now and I know men in their 60s who've been trapped and emotionally blackmailed by their wives for 20 years.
Which is precisely why you should date women younger than yourself. I personally know a 23 y.o. smokin' hot HB 8.5 who's seeing a 38 y.o. guy - her first 'older guy' as she puts it - and she cannot get enough of him. I was also the best man for my best friend's wedding last year, his wife is 25 and he's 38. They started dating when she was 23 and he was 36. Again, don't buy into what women who waited too long to cash their chips in in their 30s would have you believe about young women and older men.
