BF is charging me for paper towels???

So I rescued two gorgeous puppies and I explained to my bf that they were not yet potty trained but we were working on it.

He said he understands and allowed me to bring my pups over when I go visit him.

Sure enough there were a few accidents. I used his paper towels to clean it up.

After awhile he started complaining that I was using up all his paper towels.

So he starts hiding them! Really?

He continues to say it's ok to bring the pups but he's complaining 24/7.

Just FYI. He didn't even buy his stock of paper towels. He stole them from work for a whole two years before he switched jobs.

Today just paid him $$ to go buy paper towels because he doesn't have anymore and he refuses to buy some more.

Am I tripping over nothing????

EDIT: His dog had previously destroyed my carpet and he didn't offer to pay any of the damages and I had to pay the apartment way too much money to get it replaced.
