Again I must emphasize, the key concept here is that we must learn to take our emotions seriously. If you feel like you are falling in love with someone, then these feelings are of profound importance. To ignore them, demonize them, trivialize them, or deny them is ultimately poisonous to the minds, bodies, and spirits of all involved. Erotic love is arguably the most powerful and meaningful emotion in human life. The universe does not present you with such life-transforming emotions just to toy with you, or test you.
Love is meant to be acknowledged and expressed.
The best form of expression will vary depending upon the context, but in the end love is the road to a meaningful and healthy life. When we take our feeling seriously, we can no longer assume that whenever our feelings conflict with socially sanctioned principles, it is our feelings that are at fault. The socially sanctioned idea that it is only good to love one person at a time must yield to the reality of feelings, which testify to the reality that it is indeed possible and maybe even desirable to openly love as many people as you can love. I would love to hear your thoughts.
