I've seen several threads around here about women who are concerned about their girlfriends having different (or opposing) lifestyles or ideologies.
Remember that even if their decisions concern or annoy you sometimes , you don't have to judge them, because somewhere along their path, they will learn their own lessons - and if they don't, it's not your problem. Give advice to them, don't be judgemental, and after that, don't worry about any bad decisions of them (unless is life threatening!). Focus in their positive qualities that attracted you to them in the first place!
Look at your non RPW relationships as a way to practice tolerance and acceptance. Being friends with people that think different from you is a beautiful thing! And remember that if their ways annoy you, it says more about you than about them: you might have to work on your patience, tolerance, or detachment (OF COURSE, im not talking about bad friends who ignore or disrespect you in any way. Those are the ones that you definitely need to ditch).
I've got only one close friend who is RPW oriented. Some of my friends are feminine, others are masculine...bitchy, sweet, liberals, conservatives, feminists, not feminists, superficials, intellectuals, idealists, pragmatics.... I get along with all of them and love them very much.
I'm pretty sure that some of my girls saw me as a trainwreck in my partying years but they never put me down for it, they just gave me some advice and left it up to me. Some years ago, I COMPLETELY changed my life and my way of thinking, and my friends still love me (probably a bit more because now im sweeter and gentler!) even though I might seem like a different person.
Of course, it's sometimes hard to keep friendships with people you find yourself having less in common as time goes by... But you can do it and be happy with it. For example, I don't go partying with my junkie raver ex BFF anymore, but every couple of months I call her to grab a beer or a pizza and she tells me a ton of whacky stories that make me cringe a bit but also laugh a lot. We have a blast each time.
Avoid friends who judge you for being RPW, and friends who try to pressure you to do stuff you don't want to do. And if some of them disappear after you become RPW... Good, they are showing you that they weren't your real friends in the first place - that leaves room for more genuine friends.
Just some thoughts!
