Space is not expanding. Space is the presence of nothing / the absence of anything and everything. Double nothing is nothing. Zero times anything is zero.
Stuff (or matter) within our view (and beyond) is not expanding (like your gym shorts). Rather, the rocks, gases, celestial bodies, all the stuff out there, is spreading apart (putting distance between each other).
Space, the cosmos, goes on forever, regardless of whether or not there is "stuff" floating/traveling/flying through it or taking up residence in it. Space is nothing, and nothing goes on forever. It does not expand. If someone tells you otherwise, then ask them what was there before space "expanded" to there.
