Why did Gulliver want to return home?

In Part 3 of Gulliver's Travels, Gulliver hears through Flimnap that he's in serious danger. The Queen of Lilliput and the High Admiral Skyresh Bolgolam are plotting his downfall. They've drawn up a list of crimes against Gulliver, including the most serious one of all: high treason. Although Gulliver's a hero in Lilliput for putting out the fire in the royal palace by urinating, he technically broke the law. Passing water in the royal palace is high treason, punishable by death. As for Skyresh, he's insanely jealous of Gulliver for his heroism in repelling the Blefuscan invasion force.
Suitably warned, Gulliver swims to Blefuscu, where the natives help him escape in a rowing boat of his size. In the distance Gulliver can see a flotilla of Lilliputian ships heading in his direction; they're coming after him. At that moment, Gulliver wants nothing more than to be back in England with his family.
