I have a friend who is probably in dire need of trp. He has a girl that he has been interested in for over a year, who he's been friends with, and she keeps stringing him along, "maybe it will happen some day" etc. She talks about having sex with other boys in front of him, but gets upset when she sees him with another girl, and he feels guilty and never sees the girl again. She fucks boys on tinder, but says it's too soon to do anything with him. I've told him several times to cut her off, but his feelings for her seem too strong for him to do it. If he tries to, after a few days he gives in and texts her or something.

I've looked through this sub a bit to find the consensus wrt telling your friends about TRP and it seems just to be "don't". I discovered TRP a couple of months ago, and have slowly been implementing some of the basics in my life (fitness, reading, nofap, not really any PUA stuff because I'm already in a LTR), so there aren't really any noticeable changes on the outside, so it's not like I can say to him, "look how much this stuff has helped me", but at the same time, if I know the solution and I don't tell him, I feel shitty about it.

Any thoughts?
