Check the pulley itself. The bearing may be bad too. Also, check to make sure all pullies are aligned.

All 3 pulleys are aligned but the tensioner it seems to be a lil closer to the engine than the rest causing the serpentine belt to not be on that pully all the way and over time it causes the belt to break I dont know if its the pully or the whole assembly

If that is the only thing out of alignment, chances are the bearing is bad. Remove it and check for play.

How would I go about just removing the pully wheel?

Just to add to this one sounds like the belt tenisor arm has shifted causing the pulley to be out of alignment. Same thing happened to my saturn and tore up the belt. If the bearing on the pulley failed you should be able to grab the pulley and feel the pulley being wobbley. Most likely you will need to replace the belt tenisor.
