Is it okay to not leash my jungler?

Now Hear me out. Don't get all high horse right of the bat. I play lane bullies. Renekton, Urgot, Darius that kinda stuff. Now In my elo my jungler rarely ganks, and if they gank it's almost never top. So is it okay for me to not invest time into them, knowing with almost certainty that they aren't gonna return the favor. My friends all say that I'm being an idiot and should just help them. But I really don't see the point in possibly losing 3 minions worth of exp and my position in lane for someone who I won't see for 20 minutes.
