monogamy rules

I think that it is possible to really, truly love someone and still think about someone else, or even be curious about another person enough to be seriously drawn to this third person. But simply because we live in a society where, although it doesn’t work, monogamy rules a person cannot be free to act on such an impulse without facing impunity and demonization. I think you can be drawn to another person enough to want to experience something with them just to see what it would be like. Or maybe just to reassure yourself that what you have is better and more real. If desire itself is a form of betrayal, then how much more harm would be done if those thought were put into action? One would think that, ideally, you could go back to the person you love after all is said and done, when you realize that it wasn’t what you thought it would be which I think is always the case. And if by some rare chance that it was wonderfully amazing, wouldn’t you have rather experienced that moment of bliss and adrenaline then always wonder what could have been?
