Back when I was most active in the dating game, there was no internet, not theories. You just had to go and experience rejection and find a way to get fewer and fewer rejections. Maybe, if I had access to the amount of information that is available now, I would also be struggling with 'information paralysis', but dating was a lot simpler then.
Also, most of my 'relationships' last anything from 6-9 months to several years. I've had seven one-night-stands and three of them led to longer engagements. I'm an Einzelgänger who used to have polyamory relationships before they had that name for it, and I've been in a LTR for sixteen years (12 of them married) with two children. So I can give some information about what I know and experienced, but I also know that many things I did or didn't do are not replicable by people who are not me.
And I found that monogamy and marriage are not my forte. I feel better, post-divorce, just living by myself with my children and having several girlfriends who are aware they're sharing me. For me, that works fine, but I can imagine that a lot of men wouldn't be able to do the same. Nor would I expect or advise them to follow my example.
As for the RP, I don't believe in any of the pills. I believe some people get tricked into living other people's fantasies, but you should find your own way to deal with other people.
