Destined relationships are indeed noticeable in Tarot readings, but will also show if we are nurturing illusions and bad choices regarding love partners and current relationships. All divination methods I use will show how important are persons my clients are interacting with at this moment in time, is it permanent or temporary experience.
There are many soul mates that we encounter in our life time, father, mother, sister, brother, best friend, lover, husband, wife, cousins, even those people who who utterly detest for no reason, but who, as a result of us knowing them, we are pushed on to another path. More often than not this question is really about, have I met the one person who I am going to be with forever.
