Gravity bends space?

If gravity bends space (and therefore elliptic trajectories of celestial objects), then why do comets breakup due to tidal forces? Shouldn't they glide (stretching and shrinking) through the space as it is (bent or not)?

What does it mean for space to be bent? What does it mean for objects that exist and travel through that space.

Wtf, guize, I'm confused with relativity theory and all this gravity bends space thing.

nb4 troll. please, discuss.

Comets do breakup due to tidal forces (lookup "Roche limit").

If bending of space tears things apart then we could say that the object is torn apart by being stretched between the curved space itself and some ideal flat space. Otherwise, the object should follow the curvature of the space with no resistance (which does not happen).

In my opinion bending of the space does not occur. Only objects acting upon each other by gravity.
