Im stuck in leafgreen im on island 1 2 3 and i cant leave to get my sixth badge which i should have got before i went to the island how do i get off?

ok all you have to do is this go to the guy near the boat and talk to the guy and he will ask you what island do you want to go to if your at island 1 he'll say island 1 2 or the city you went on the boat at if your on island 2 or 3 he'll say that city island 1 or3 if on island he'll say that city or island 1 or 2

I have the same problem and this isn't true... This man that you are talking about only sends you to the other Sevii Islands unless you do a bunch of other stuff.
