Both can be true: Russia can lack numbers to make a strategic breakthrough, and Ukraine can simultaneously not be able to field enough materiel to be able to recapture their losses.
IMO the most likely outcome is a stalemate that turns into de jure conquest of the territory Russia has captured and it turns into a cold (or at least cooler) war.
Same here. Been together 8 years, and from the sounds of it they got terrible ~7 years ago.
