Galaxies don't really end or disappear. Stars can take a few billion years to die, but it's all part of a cycle that feeds new stars.

The black hole in the center could suck up all the stars if something were to throw them out of orbit.

A collision of two galaxies is unlikely, but it happens, and if it did, many stars would be flung into space. But 1 galaxy would be formed as a galactic sandwich.
