Yes the universe will end, but at the crunch the process starts all over again, and could go on forever (cf. Hindu and Buddhist ideas of re-birth). Another possibility is "multiverses" - there are lots of different universes, all in different states of existence, some at moment of big bang, but will never become a universe as we know it, so grow to the size of a grape and shrink back, or expand outwards and never turn into frothy, lumpy matter - just a thin soup with no life in them. Our universe is perfect…not too fast to become a soup and not too slow so it falls back in on itself to destruct - just lumpy enough for galaxies to form and the whole thing hold together - a balancing act between gravity and acceleration, for the time being.
