Hi RPW

RPM here, I've always been curious to know if women were able to look at another woman with her boyfriend/husband and can instantly tell whether or not that woman is in the relationship only for resources/companionship (a beta) or because she truly loves him (an alpha). Or do you have to be close friends with the other woman to tell? For example, could you tell if the woman in this relationship is truly in love: https://youtu.be/Zb1CgY-_qNg?t=1m20s ?
