This is not true. I am a single, middle aged woman with no regrets.
When I run into exes, I don't see lost opportunities. Instead, I see choices I made in the past that would no longer serve me today.
Life is not all about getting married and finding "the one " but if you make it so, then you may miss out on a really great life while you sit around crying about what you don't have.
If you are single, enjoy you freedom and have all the adventures you dreamed of. The REAL truth is.. you can be a happy, single, middle aged female and most of us are!

Women get 10 prime years to snag a dude - between 15-25.

What women fail to understand is this is reality...why? Because a 27 year old dude can have his pick from any number of super hot 18-20 year olds, whereas a 27 year old woman is forced to go with older guys, most of whom are either already married, or have a "past" which they won't probably like very much.

When we're under 20 the girls have all the advantages, which they need to have as they're the ones instinctively looking to find a mate.

After 25 the advantage tilts 180 degrees in the other direction.

It’s not everyone’s destiny to pursue the white-picket-fence dream.

I find it hard to respect people who just go along with the programming that you "should" get into a relationship and have children.
I prefer being independent and travelling and having time for things.

is skin deep and time limited....

I hope that by requirements you don't mean needs. There is no person in the world aside from yourself that can and should meet all of your needs. This is where we go terribly wrong, thinking that another person will make us whole. If requirements are deal breakers such as he's a 30 year old living with his parents and broke, then ok, these deal breakers are needed. I'm a firm believer that we attract who we are so the responsibility is on us to work on ourselves so that we're not attracting undesirables.

This made me laugh out loud. I'm in my 40's and I am swatting them off me. Young, old, you name it. I have no need to "snag" a dude because I am not desperate for a relationship. Life is really good. Why would I get married? Marriage is only good for men.

Yeah sure you are. And that's why men are complaining "there's no women in Vancouver,where have all the women gone?" NOT

@Lol
A good, deep and reciprocal relationship can be very good for a woman.
Whether marriage or other, this is true but also makes such a thing hard to come by. Which would be so with anything that takes a lot of trust, work, respect, love and compromise.

I know someone who just got done (amicable parting) with a 15yr marriage (relationship was even longer). Going in, she was a regular heavy-to-binge drinker, size 16 and not OK with it or healthy, serious cancer risk (close brush with cervical), light smoker, depressed, insecure, stressed out workaholic executive.
For the last 7 years she's been size 4, athletic, best shape of her life. Healthy, happy, nonsmoker, occasional light drinker, not so workaholic anymore. Marriage (in this case) has been VERY good to her.

It really depends on the relationship and the partners. A truly good partner is hard to find.

All the single ladies I know are really satisfied with their lives (aged mid 20s to mid 50s ) but can't say the same for the depressed married women who are treated as the unpaid, household caretaker that has to be home before 10pm.
Nope. I won't be crying to still be single at 45!
