A new nova evolution model is used to resolve the apparent discrepancy between the observed mass accretion rate (MAR) in prenovae and in old novae and the theoretical upper limit to the MAR which yields a thermonuclear runaway. The model offers a plausible disguise state for very old novae as well as unifying links between old novae, novalike variables, and dwarf novae. The model predicts that mass transfer must cease in a cataclysmic binary a few centuries after eruption, remain off for millennia, and then resume. The effects of such long-term variability of MAR on a white dwarf are studied, and the implications of the results for the long-term evolution of novae and related catalysmic binaries are discussed. 32 references.
