That's an interesting question. Recently I did a reading for myself about someone that I'm involved with. For 'why he's in my life' I got the 6 of cups, and for 'why I'm in his life' I got The lovers. I'm still mulling over what these two cards together mean, but he is someone from my past, someone that I've known since I was 15 which wasn't that long ago (we're 21 and 22) but I suppose we were in between childhood and adulthood when we first met. We both always wanted each other but never got together, and have never stopped wanting each other...the feelings for him just don't go away. Lately I've been thinking that it's probably a relationship that needs to be explored, otherwise I will always wonder what if. Whether it's love or not I don't know yet, it's still kind of new and I'm still processing my feelings about it. I kind of just have a feeling that he's meant to be in my life and that us together is so right. Is he my soulmate? I'm not entirely sure about the concept of soulmates. I think it's often defined in this really romantic way, that it's our one true love. I think we probably have many soulmates like canid describes, and I don't think a soulmate would necessarily be a lover, it could be a platonic friendship too. I prefer to think of each person that's in our life being in it for a reason, to give us or teach us something...and we have deeper connections with some than others. Some we stop caring about, others we never stop loving or caring for, some stay in our lives for a long time and others leave.
So I think the 6 of cups to me could be a relationship which has a history, is tied to your past or childhood somehow and which has a feeling of fatedness to it. About a month ago I woke up with this very clear thought in my head that I had to call him right now and re-establish our friendship...it was most strange. I don't know if I had a dream or what, but I woke up with the epiphany that I need him in my life.
