I have mixed feelings on this. I think we can love multiple people in our lives. But when you are in a very long term, good relationship . . . after a lifetime together, it's hard to NOT believe you were meant to be and soul mates.
No, use to think that as I was younger and thought I was happy, still think I'm over all happy. But hormones, life issues and other strained put that Thought out of my mind...it's just a happy feeling for the now. Confuses the mind.
