I too believe that marriage is socially constructed and agree that monogamy is not our natural way of being. I also believe though, that loving someone is a choice, and that we don’t just fall out of love with our partner. I also think that it is normal to feel romantic love for someone other than your partner, but that we have been conditioned over much time to believe that this is highly unacceptable and immoral. Because of this, I can’t see an open relationship working very well, unless you were raised by wolves!! It is great to understand and be aware of all of the social constructions that we live with, so that we can accept ourselves when our feelings and natural instincts go against the norm. In the end, I am happy not to be ignorant, but also aware that I have to live in our society!!
