I've just seen this episode of pll Over My Dead Body and Spencer & Toby break up there. But in the future, are they getting back together?

yes,they will

yes of-course they will get back together.they both can't survive without each other.actually we cant tell that it was a break up.it was just an argument & then Toby did not appear in any episodes other than in black & white episode.so we cant tell exactly that they have broke up...even if they break up, they will get back together as soon as possible...
