What do I do now!!!

i recently posted about a weird noise coming from a area under the hood and thought i had it fixed. today iwas driving home and the pulley connected to the supercharger snapped off, not the on connected to the supercharger but where the two are right next to eachother. i opened the hood and the belt was just setting there ( thank god it didnt get wrapped up in anything) and there was supercharger oil splattered on the hood and a little bit of engine coolant, wtf happened and is it fixable?

I found out what i need but idk what sizes to get i have 3.4" supercharger pulley and i the tensioner and idler pulleys but idk what size, still havnt found out what caused the SC oil to splatter all over the inside of the hood tho. and the coolant was from the break slicing the hose so thats fine now. PLEASE HELP!!!

All pulley sizes are in the pic below. Substitute the 3.4" drive pulley for the stock 3.8". Check the front of the supercharger snout and all other areas of the snout to be sure. You may have a bad snout seal causing the SC oil leak.
