My Clutch is being weird!

[elixxur]

So I decided to open up the car on the yesterday since I baby it a tad much. I am the second owner, purchased with 5k miles back in feb, it has 6k now. I didn't ride on the clutch just did normal shifts and revved it to 5-6k on the freeway. Shortly after entering the freeway I noticed my clutch felt looser. In fact, at one point it stuck once to the floor.

After letting my car sit for a bit, the clutch felt a little more tighter, but still not as tight as it did prior to driving fast on the freeway. My friend thinks maybe my pressure plate or ball bearing is messed up, or I have air in line. I've driven at similar speeds in my Abarth and experienced no anomalies like this with the clutch.

Thoughts? Anyone else experience their clutch getting loose?
