Am I right to insist on him paying to ship it back to return the loaned property?

I loaned a laptop to my boyfriend for a month (no official contract, just text messages), so he could use it for his online classes. We broke up and I asked to return my things by mail. He refuses to mail it back, saying he won't pay for shipping. He insists on meeting face to face or letting him into my building lobby. I view this situation as a bailment, where he's a bailee whose duty is to return my property according to my instructions. It doesn't cost more than $20.
