How long were Jack and Kate together when they got off the island?

oh i don't know cause they didn't tell us but i think for 2 years atau maybe 3 years cause ARON was 3 years old and some months after they went to the island so i hope i amn't wrong cause i cinta jate and answering to fan

About 3 years. They didn't tell us how long it actually took for them to get together, but I'm guessing it wasn't that long ;)

And their breakup, I think, was pretty close to the time that they went back to the island.

Between 2 and 3 years, I'd say. The entire time off-island lasted 3 years, and obviously they weren't together for all of that time, but I don't think they were apart for lebih than a tahun in total.
