(((Veryregretful)))) Please read my prior post from about 3 weeks ago, my AH did almost the exact same thing as your AH. It does get easier with time, trust me, it really does. What I did w/my AH's things that he still left around the house was, went to the liquor store, got some boxes and packed up the rest of the stuff and put it in my shed. I let him know that's where it is. When he comes to pick it up, maybe it will send a message, maybe not. Not my problem anymore.
Stay strong. You are in no way to blame, so please don't take it personally.
Hugs
