hey go out a few times and she begins telling him very intimate things. At this point, they are texting daily. Then suddenly, she goes silent. He reaches out and she basically tells him she just wants to be friends.

He was the emotional support tampon and plan B security blanket - giving her the confidence to leave the guy she was with and chase somebody else.... who she then got...then the LJBF chat.... and who has now dumped her.... hence the chatting again.

My question is, is this common?

ish.

Women like this prey on and manipulate nice guys who follow the beta programming of "give endless love and attention and pray for eventual marriage".

They absolutely know what they are doing and have a range of come-backs lined up if ever the situation changes. She has lines literally ready.... "I didn't know you felt that way"... and she has lines ready for if sex is a possibility... "I really like you buy I'm not quite ready for that yet".

Additionally, would not responding/responding “no” to her LGBF offer affect this outcome?

Yes.

None of this makes sense to me as a 3rd party observer.

It should if you've been around TRP for a while.

Your friend needs to learn a few lessons. Being an emotional tampon gets you used. You give away all power and get nothing.

So don't be a fucking emotional tampon. Lead with looks, charisma, style, attractiveness. Try to fuck women. DITCH WOMEN WHO ARE NOT FUCKING YOU.

As a beginner at age 18, you should ditch a woman you have not had sex with in 30 hours in her company. At 30 hours you're in the friendzone, but you couldn't escalate faster.

Intermediate at age 25, that should be 20 hours.

Man of the world at age 30, that limit is 10 hours.

If you've been in her company for 10 hours, presumably attempted to escalate to being alone together and then to sex.... if it's not clearly happening at 10 hours, time to NEXT.

The next can be quite soft... you can fade them out..... or even accept them as friends (ie MUTUAL BENEFIT) but you most definitely should filter out the timewasters at 10 hours and put your efforts into women who might want your dick bashing their cervix.

I mean "diminishing returns" and here is my case:

Fair question, but we can't answer this for you. We don't know what else you could do with the money, nor can we know the benefits.

I got a 07/10 shape. To reach 9, i would have to restrict my diet to a point where fucks social events, or hop in test which is stupid (moneywise and add more unecessary variants to life)

Ok, you need to get to 9/10 for you. Women do not like average, and 7/10 is average to women. I think you're making excuses here.

Getting to a 9/10 body needs fuck all money.

I got a 07/10 job. (12k month afer deductions/ 12h shifts/ 12 times a month). It's enough for my demands, i get to invest 3k a month and at the end of ot i still have another 2-3 to spend as i like or save. Any effort into improving it would mean diminishing my free time.

Fair.

I got a 05/10 car. Improving it would mean wasting a lot of money without any real benefit apart of "showing up myself".

Shit car..... ok. That's fine for casual sex. Might be worth improving if you want quality women and a promotion. Very expensive, marginal gain.

Same for my house. I live in a 36m² apartment where i have exactly everything i need, i never spent time searching for things and get it cleaned in no time. Moving would mean diminishing my free cash.

Well. Again, we don't know how much cash to upgrade vs what else you could spend the money on.

Good house is impressive, but it's "money/relationship" impressive and not "fuck me now" impressive. The main benefits of a great house are hosting great parties - and that can really get you girls. Location, lifestyle, hosting make a big difference to your social life - for some amount of money.

I got an eye surgery. It was expensive but now i'm glasses free, which makes me more attractive and more functional in life.

Yep.

I'm debating the hair transplant. It would make me look younger and eliminate one handcap with woman. To be honest, materialisticwise i feel it's the last one. But it's expensive, gives me zero "functionality points", and I could travel the country twice with this money.

Or shave it off / have it really short. Some women really like that. So this isn't a clear win. Wear a wig for a day if you think it will make a massive difference, ie test it.

In a broader approach, i'm debating how much more effort and resources spent in the material world is really worth the return. Or if it's better to stop already and shift all into life experiences from now on.

Obviously we can't answer this for you.

But what I would suggest is simple ROI. Work out how much money to save or invest (house, stocks, savings account, whatever).

The stuff to spend: work out what benefit and what cost.

Eg: Hair transplants: $10K. 10% more attractive to 50% of women. Better house / social / hosting: $2K / month. 50% more social opportunities. Car: $25K. 100% more attractive to gold diggers. 10% more attractive to normal women. 10% chance of geting a $10k promotion.

The hard part of this is even wildly guessing the returns. If you want more women, there's almost certainly more you can do for free by finding ways to meet more women.

My buddy is a very good guy - big heart, but is fundamentally unable to be RP’d (I have tried countless times).

You can't truly Red Pill another man. Only women can. All of us here have suffered and been broken at the hands of women, and had to rebuild ourselves from the ground up.

Please also give me tips to get him away from this woman.

You seem to be more obsessed with her than you are with him. It's not your relationship, so just leave them alone. Your interference will only serve to drive a wedge between you and your bro. She's got her claws in him. He's dumb, deaf, and blind, and if it comes down to it, he will pick her over you. Is that really a risk you're willing to take?

You can warn him and warn him, but he can't hear you. He's stuck inside this bubble that only he can come out of on his own. Your job as his friend is to wait for her to shatter him, then be there for him to help pick up the pieces.

Like @Typo-MAGAshiv said, the only way for hard core Blue Pill men to learn is to suffer through the pain of making their own mistakes. It's all part of the journey. Yeah, he's in a bad situation now, but he will eventually come out on the other side, and he will be okay.
