I have to admit that it does bother me when I see a woman I'm attracted to with a weak man, I feel sorry for the man. I honestly really don't do anything about it, I just realize eventually all that will come crashing down. She'll dump him for a real man, or she will make him so miserable that he'll want to kill himself with alcohol, which she cheats on him.
If I like the guy, I'll try and help him, but trying to help a committed Beta, 'blue piller', is very hard. They have to get kicked in the teeth really hard. A good friend of mine now, and occasional wing-man, was a feminist weak @ss Beta. Had this Earth muffin girl-friend who was a 'life-coach', and waitress. She was super cute, and he waited on her hand and foot, gave her everything, kissed her butt, well.... you guys get the picture. I tried to help him.. telling him he was too accommodating, always apologizing to her, that they were headed for trouble. One day he went to her restaurant to surprise her after work (She worked at Commander's Place, (a high end place Uptown New Orleans), and her assistant manager had her bent over a table in the kitchen fvcking her. They both yelled at him to get out, and they kept on going... Jez, just thinking about that makes me laugh... I know I'm an a-hole... but sh!t.... all that was completely predictable.
Anyway, this was about a year and a half ago and now he's done a complete 180, Took 6 months off of dating to work on himself, working out, he read every book I recommended to him (No More Mister Nice Guy, The Mystery Method, The System, The Book of Pook, DJ Bible) really those are the only ones you need. You really don't need to waste your time with PUA stuff but that stuff does work, just read "Mystery Method", everything all these PUA coaches teach are in that and the book is very objectively written without a bunch of stupid anecdotal BS stories about how the PUA used to be a weak @ss Beta.
Anyway, he's doing great now, even stole a couple one woman right out from under me LOL!!! He's a big Star Wars geek and is always kidding around that I turned him to the 'dark side'.
