For an object to fly apart, it must reach the breakup velocity (due to centrifugal motion) that will overcome both the force of gravity on the object and the stiffness of the material it's made out of. Simple, back of the envelope calculations will show you that the despite the high velocities exhibited by the rotation of neutron stars, the force of gravity of these stars, alone, is sufficient to keep them from flying apart...let alone the stiffness of the material they're made out of. If it was easy to write the equations down in these posts, I would, and you could the calculations yourself, but these forums don't allow you to write the equations (except for simple ones) very easily.
