It all makes sense now.
The reality is nowhere close to this.
Strangely enough, gaining the strength to leave a destructive relationship is a soul mate test! Spiritual chemistry is when you see life through a similar existential lens; your hearts are at home because you value the same things: kindness, generosity, loyalty, friendship.
So, a soul mate could even be a boss who supports your career and helps you move forward, a teacher who devotes that extra time to you, someone who backs your idea or believes in you, a friend who is always there for you, no matter what.
