Hi and welcome.
He asked you to throw it away, so why don't you? No need to return the paperwork if he doesn't want it. It's not your problem.
You could mail the yearbook only perhaps.
As for telling his family, what will that help? They know he is an alcoholic, none of it will be news to them.
To be honest it sounds like you are trying to hold on here and I totally get that, it's a huge shock and I'm sure you are hurt.
The first thing you might want to do is write a list of every terrible thing he has ever done and/or said to you. Just in point form, so when you start to think about the tiny "good" times, you can refer to the list, even 20 times a day if you need to.
Starting focusing all that care on yourself. Spend time with your own friends and family as much as possible. They might not understand your relationship at all, so no use explaining it if you don't think that would help, but being around people you like and that care about you and are "normal" can be really comforting.
When you said you "forgave" the money he owed you, you mean you stated to him he didn't have to pay you back? If so and you texted it to him, well that's proof. Otherwise you could try to sue him for it in small claims court perhaps.
