Particles with the same mass form a representation of the symmetry group. That implies that particles are paired in
the case of SUSY. Physically, the Hamiltonian commutes with the susy-generator. The susy-generator therefore maps one eigenstate to another. (A boson with a specific mass to a fermion with the same mass.)

When a symmetry is broken, it means it implies it does no longer commute with the Hamiltonian. The above reasoning breaks down. Depending on how the symmetry is broken, the mass of a particle may become much higher than that of its
susy-partner.
