How to make another script stop running after it has been destroyed?

The script below destroys the other script which is just a tween move script but after it destroys the script, the script that has been destroyed still runs. That means its gone from the workspace but it still has the effects. Why is that and how can i fix it? Also i am new to scripting so please don't criticize me, thnx

local CurrentPos = workspace.touchablepart.Position

if workspace.touchablepart.ClickDetector.MouseClick then
	workspace.MoveScript:Destroy()
elseif workspace.touchablepart.ClickDetector.MouseHoverEnter then
	wait (.5)
	workspace.touchablepart.Position = CurrentPos + Vector3.new(2,0,0)
end

you cant destroy the script and make it not run anymore (at least i think.)

you also cant do this: if workspace.touchablepart.ClickDetector.MouseClick then

do this instead:

local CurrentPos = workspace.touchablepart.Position

   workspace.touchablepart.ClickDetector.MouseClick:Connect(function()
    workspace.MoveScript.Disabled = true
end)

workspace.touchablepart.ClickDetector.MouseHoverEnter:Connect(function()
    wait (.5)
    workspace.touchablepart.Position = CurrentPos + Vector3.new(2,0,0)
end)

this should work.
