Yes, I think it is possible, Mia. But only if the people are not forced into the relationship and if they are satisfied with themselves inwardly. People can seem content with themselves yet always yearn for external stimuli(multiple partners) to fill the gaps within. I think it is most important to have a relationship with yourself and, if you believe in this sort of thing, a relationship with spirituality. I don't mean religion, though. Just having a connection with the divine consciousness, which I personally believe exists. I think relationships are just mirrors of yourself. We seek and attract those that will complete that part of us that needs attention. I think romantic relationships are beautiful and special, but really, they are just reflections of ourselves, what we would like to see in ourselves. So of course when we feel lonely we will seek a relationship, even if it is outside of our own. Of course, if we see beauty, we may instinctively want to merge with that beauty not only for biological reasons but because we want that beauty in ourselves. Of course we will want to run along side someone that makes us feel free because we value freedom. But if we realize that we all are a part of god source and that we are already complete as we are, then we will be able to attract one who feels complete also, and with whom we feel satisfied to stay with exclusively, without feeling any pressure. So yes, I think what you have proposed is possible if their is a greater understanding of all things.
