Honestly I think you focus on the wrong thing. First and foremost, I'm with the xNTP, everyone manipulates, big deal its how we interact. Don't be a dick about it. If you really want to deal with this then step one is to not lie to yourself, stop talking about out of nececity, doesn't matter and retracts/diverges from your problem. You want to deal with it, not shift the blame. Lie to others, but at least be honest with yourself.
But if you feel like the less people you interact with the better or what not, then you have bigger things to deal with than being afraid of manipulating others.
