Is AUTHOR wrong in the post ? POST : I'm going to be completely honest, this is solving an issue he and I are having, we both put full consent into this. Every single time we have a D&amp;D session everyone including me pitches in 1-2$, so we can buy new books.

I put them on a bookshelf and my friends come over to grab books when they want. It's really convenient. He and a girl in a group (leaving the age out of it, it was legal though, so no worries), broke up after he cheated on her 2 times, he's guilty but is being outed out of the group (Not my choice, so don't use that against me) he probably donated a total of 50$ but constantly use the books, he always had at least 2 books, he did give them back though.

He now wants a couple books worth $145 total, even though he probably only pitched in 45-60$, which I find is ridiculous.

Am I the asshole for not giving him any of the books, I mean he used them for 2 years, which is great knowing we have 600$+ in books in our collection as we play different editions of D&amp;D (Oldschool, 3.5e, 5e) so it's a big collection. 

To conclude, ATIA for not giving him any books after the fallout as he used them over the two years. (Be honest, you don't have to be nice about it, let it all come out, thanks)
