Liz actually pointed out another scenario to me, which is that, a lot of the time, people come to nonmonogamy when they're already in a committed, monogamous relationship, and then they start having an attraction for someone else.

莉兹实际上向我指出了另一种情况，那就是，很多时候，当人们已经处于一种忠诚的、一夫一妻制的关系中时，他们就会转向非一夫一妻制，然后他们开始对别人产生吸引力。
