Jake Paul wants to settle his feud with Tommy Fury once and for all ... saying he'll fight TNT in the U.K. in February -- or he's moving on forever.
The Problem Child announced his plans in a message to Fury's promoter on Tuesday ... saying, "Dear @FrankWarren, I agree to fight Tommy in Manchester or London in Feb. I’ll come to his country, no more running."
The fight has been cursed since the very beginning -- it was scrapped twice due to issues on Fury's side .
