I'm 50 and soon realised OL dating is full of men in their mid 50's who want a woman aged maximum early 40's
They seems to have magic mirrors as what they think of themselves compared to the reality is worlds apart
I find IRL men are more liable to speak to and date women more their own age whereas OL they seem to be more deluded
This is true.
I have heard tales from many women aged 45 to 58-ish, who go onto online dating... Most men roughly their age, want women a minimum of 15 years younger. As has been said by many on this thread, these men see themselves as hot, desirable, wise, and appealing mature men, who will surely attract women a generation younger. Most of them are balding, going grey, have pot bellies, are too hairy, and are boring and moany.
Unless a man is very wealthy, most women in their 20s and 30s are not going to be interested in a man old enough to be their father. I do wonder (as a few posters have said,) if men don't want women their age because they won't take any shit. But also, I think they want younger women, because they think they DESERVE younger women, (as they, themselves are so 'attractive' still!!!)
They see younger women as better than middle aged women, and they think they deserve them.
Also, for many men aged early 40s to late 50s; middle aged women are repugnant.
I am in my mid 50s, and although I am OK looking, I pretty much look my age (as almost everyone does.) I get young men (say, under 38,) being very polite and courteous with me, and older men (65+) being friendly, and nice to me.
The group in between, look at me like I am nothing. They don't even look me in the eye. They don't want to show any kind of friendliness towards me, in case I mistake it for them fancying me. Coz God forbid I think they fancy me.
Why would they fancy an old biddy in her mid 50s, who is way past her sell by date? PMSL!
Men - especially middle aged men (early 40s to late 50s) are a funny breed. They truly believe that THEY are really appealing and attractive, especially to much younger women. Yet at the same time, they think women their age are repugnant. Bizarre! 
As a few posters have said, if me and my DH were to split now, I would never EVER want another man. I mean, what would I get? A man of 65+, who will expect any woman he is with to be his bloody personal servant, and cook and clean for him and do his washing and ironing? Fuck that!!!
I remember one woman I know arranged to go on a date with a man she met online. She was 46 and he was 50. The first thing he asked is 'can you cook?' The next thing she did was cancel the date. She said 'if that's all he is interested in, he can fuck off.'
Even if I get a man my age, he will probably be a whinging, moany, grumpy old curmudgeon. Many men over 55 are!
Nah, fuck that. I would rather spend the next 35-40 years on my own (if I live that long!) rather than spend it with a grumpy, moany old man,!
