I think you grow in the direction you are pointing in. So its important to be aware of that direction moment to moment.
I have been in a relationship for 15 years
It's like running together holding hands.
it takes constant tending and adjustment every moment we become different people.
every time I ask "who are you now?" I get to fall in love again.
It's important to ask clearly for what you need and it's important to be totally honest. Not brutally but gently totally honest.
its not a walk in the park its flying a plane you have to use autopilot sparingly. There really is no substitute for constant vigilance.
For me I feel we grow together by growing in a simular direction. That is a constant choice. So I suppose yes if you are not choosing to grow in a simular direction to someone then you will grow apart.
