has been searching for someone on these sites (including the one mentioned in the OP) for a decade, and she gets the worst men. Horrible. Last one was a 4'11 CPA with an AHEM rather large tummy.
And she's 5'3"!
Like the OP, my friend is high IQ and I keep telling her that unless she's able to find someone of comparable IQ, it's not going to work. And sure enough, she was dating some average jerks from these sites and they were unable to appreciate her.
One she dated ghosted her TWICE!! Just disappeared off the face of the earth. She tracked him down, gave him a second shot, and he disappeared again.
She is definitely trying too hard.
Now, on the other hand, I know a guy who is high IQ and could care less if he has a relationship. He told me he's been through that twice and knows what it's all about. I said what is it all about and he replied that it's about him getting the job of cleaning the bathroom when the household chores are divided.
But I think because he has this "couldn't care less" attitude, he gets a lot of women after him.
My girlfriend, however, wants "boyfriend/girlfriend" way too fast.
After seeing what I've seen of my friend's experience, if I were single, I would not touch these sites. I would just have friends to hang out with and have good times with if I couldn't find a romantic interest.
