What does it even mean that space is curved

I saw on another post that it is curved intrinsically and I get what that means but not really what it implies. What evidence is there that it is curved other than satisfying mathermatical equations? I get that around planets space is "curved" as in things will move towards or around it, but why isn't it just moving straight through space and something pulling me in. I feel like there is a difference here between the form of space and content of space, what is *actually* curved, space seems to me just to be a relation between objects, how can it be curved as a thing? Can't I always just draw a straight line in space through objects? What is actually curved when you say space is curved, I guess I need some clarification on a definition of space as well. 

Sorry if a lot of similar questions have been asked but reading through them I felt none of them really cleared up my confusion.

Light follows the shortest possible path, which one would expect to be a straight line. However, near massive objects like stars, light actually follows a path that is curved, meaning that the shortest path is not a straight line, it's curved.
