Do gravitational waves weaken over distance?

And, in case they do, what are they interacting with that weakens them?

Far away from the source they weaken with an inverse distance square law for their power and an inverse distance law for their amplitude, just like all other waves - as the wave spreads out over a larger volume the intensity goes down.

There is a non-zero interaction with matter that can reduce their intensity in theory but that is completely negligible.
