Okay well I didn't make it to the store before I busted my knuckles, the hood of the dually (weight down by ice) slammed on my hand. I know have three lovely Angry Birds bandaids on. LOL. The belt, as it turns out, was not all the way broken, but instead half of the size it used to be. Does that make sense? So I am back and I'm checking all these pulleys. I don't know how they are supposed to move so I'm not sure if it's smooth or not, all of them seem smooth except 2, one only has a tiny bit of movement when I wiggle it, the other a bit more, but the very bottom pulley in the middle will not turn by hand, is that one supposed to free wheel? It looks like #6 on your diagram.
Here's a video of the wiggling, not sure if you can tell what I'm showing but whatever....

Saw your video. Bottom pulley is probably on the crankshaft (hard to tell from video). It should not move by hand. Upper pulley that wiggles probably has a bad or failing bearing. I would guess you need to replace it. If it move excessively or "drags", this could cause the belt to fail prematurely.

The first one that wiggles is the Power steering pulley, the one that won't move IS the crankshaft and the shinier one is belt idler pulley at the top. Now can you retell me what you said based on those so I know which one you think I need to replace?

You could replace belt for now and wait for warmer weather. I would replace belt again when power steering is replaced as the new belt could be "stressed" by this wobbly pulley.

So u think the belt idler pulley is fine but the play in the power steering pump is too much right? I could have guessed the power steering was going out as sometimes when I am at a stop and start to pull forward it IS a little hard to turn.......

This is a total guess on my part. A good Ford 7.3 L diesel truck mechanic has probably seen this before and could answer these questions about both PS pump and the effect on the belt. The only good thing is that it looks like this pump is not outrageous on price. Installation cost, I don't know.
