Many theories can never be proven.
Here are a few examples:
-- The moon orbits the Earth.
-- Gravity pulls all masses toward each other.
-- The Earth orbits the sun.
-- Everything is made of atoms and molecules.
-- Atoms are made of protons, neutrons, and electrons.
-- Electrons moving through a wire make electric current.
-- The center of the Earth is molten iron and nickel.
-- The source of the sun's energy is nuclear fusion in its core.
-- Almost all galaxies are moving away from us.
-- The universe is expanding.
None of these statements can be proven. That's why they're not called
Facts or Laws.
It also tells you that some pretty powerful stuff has been done with concepts
that can't be proven. If you want to make an idea look foolish, that doesn't
happen when you say "it's only a theory".
In my opinion, it always depends on the partner how they are going to maintain their healthy relationship.
But for my opinion, here are the top 3 ingredients for a healthier relationship:
1. Communication - it is always important that you and your partner are being open with each other and being honest
2. Trust - trust is one of the most important and essential ingredients of healthy relationships
3. Commitment - how can you be in a healthy relationship if you are not commited?
