For what it is worth I am a part time longer distance commuter. My off days give me a chance to keep from getting burnt out. Plus I would say that since I am more of an enthusiast than a true 100% commuter that has to ride. My commutes are recreational rides with a destination.
Commutes tend to be loner type rides while recreational rides can be with other riders. I simply enjoy riding no matter what type it is. Perhaps the feeling will pass.
I know I burn out from time to time.
