A soul mate is established and grown with someone, in time with love and experience of life. Being crazy about is not enough. "Fatal attraction" is also often times confused with a "soulmate".
Very important people of the past, "soul mates" and the likes are oftentimes met during important planetary events. I have met someone I dearly adored on a very particular eclipse that had to deal with both natal charts. Still, it doesn't mean anything if you and the other one do not create more than this.
People oftentimes confuse attachment, stimulation, love, comfort, pleasure in a big soup with no other discriminant value of comparison. Being with no spiritual sight.
It essentially means and does NOTHING without effort for a real future. Sensorial and sentimental stimulus without realistic values and timeline of growth is on the same line of drug use.
As for your partners, as long as you are of a healthy mind and they are of the same quality as you and a human, both in mental and emotional conduit, open and interested in each other, things can be extraordinary beautiful.
