Every relationship is the mirror of you. Simple.
It is a hard concept to understand when you don’t see it. But if you choose to look deeper within this theory you will see patterns that match your own.
What comes forth in your experience is what is vibrating from within.
Even those pesky people in your space who are needy, controlling, unsupportive, addictive, unloving, uncommitting etc.
They all reflect some part of you.
