There are just going to be some people who Just don't get "it"!
there are going to be guys younger than us, who have more success than us, there are going to be guys older than us, who will have less success than us. There will be people who don't get it who will get girls that we would have wanted.
(a little off topic, but...) you can't live a person's life for them.
Just focus on your own growth.
maybe with their psychological make up they just can't be without a woman or alone. I don't mind being alone, it's relaxing.
you are being the judge saying that these guys are settling, they are settling but it's their Lives and Comfort. these women are fulfilling the role that these Men want them to fill.
sex, company, a pretty face to look at , etc...
even a bad attitude ( yeah, some men like to be dominated)
