I chose Yes/No because I'm not quite sure since I have never loved two people romantically at the same time. Infatuated, maybe, but I find it difficult to believe that one would be able to love two people equally, and all of the people involved would be better off trying to love one person to their full potential rather than splitting it between two others.
If all people involved are equally in love with one another it could work, but any imbalance in this theoretical love triangle that I imagine would lead to jealously and what love triangles usually do-- break.
