^ I don't have any problems with your values and ideologies but such things has to be shared among the two parties in a relationship. If the op's current gf is into polygamy then no one would be saying shit here.

When your partner believes he/she is in a monogamy relationship while you secretly meet others, then your just a cheater/liar. No excuse.

If the op wants to go this path, then he should let his current gf know of his decisions. You want to be nobody's? or everybody's? then be my guest and knock yourself out. Don't pretend to be someone's and act like your everybody's.
