I think if you're not currently single, you have a very different vision of what it's actually like for single women today.
A few years ago, I was a "smug married" woman with a wonderful husband, the complete opposite to what the OP described and we'd been together for a couple of decades. I thought there were lots of decent single men out there and I also thought highly of my friend's husbands.
Unfortunately, my lovely husband died and I became single.
To the posters saying "it's the OP's looks or personality or the people she mixes with causing the problems", I don't think that's the issue.
My profession is related to my looks, so I can assume that my physical appearance is decent, I am well paid, and due to a hefty life assurance payout (which for obvious reasons I'd rather have never received) considered wealthy. I am degree educated, have multiple large social circles, across most social categories and am regularly told that I am "a catch".
So, whenever I am asked if I'm dating, I say that I'm not currently, but would be willing to, so feel free to set me up with any man they know who is single, between 35-55, kind, honest, fun, decent personality, not a smoker. No one has ever been able to suggest a single person they know who fits that description.
What I have had, is friend's husbands give me booty calls (men who I didn't even know had my number and I hadn't even seen since my husband died), men who I thought were "good guys".
I've had a friend's husband who was dispatched to "walk me home safely" try it on with me, despite zero hint of interest from my side.
I've had numerous offers from hitched men to "see to my physical needs", often at gatherings with their wives in the room. And let me reiterate that I have never flirted with a married man and I certainly have never had relations with one, nor would I.
This has been a complete shock and an eye opener to me. Events that I happily attended with my spouse in previous years, I bravely faced single and grieving, only to be offered cock by men who I'd always thought were decent.
And no, I've not said anything to any of the wives because my life as a solo parent is hard enough without risking being ostracised from social groups, but had it not happened to me, I truly wouldn't have believed it.
I mix with other "young widows" and many of them have had similar experiences too.
So to all those saying "not my H or brother or father etc" don't be so sure.
Single women are not treated well by men today and it's really shocking.
