Why is he mad?

I recently ended things with a guy because he was wasting my time and not serious about me. He took the "break up" hard but understood why I wanted space so I thought we were on good terms. We didnt speak for the first 2 days after the "breakup" but on the third day he messaged me. We spoke a bit and then he offered to loan me his laptop because mine wasn't working and I needed to meet a deadline for work (he knew about my laptop trouble before we broke up). I initially was accepting of the offer but then I decided against it because it would hinder my healing period and obviously I couldn't not speak to him while I had his laptop. Also, it would have been really difficult to stay away from him after I returned the laptop. I declined the offer the next day and he got upset. He said "he feel like he has to beg me to do things and that's where he draws the line. You made it clear that I no longer want him in my life and he can't take a hint".

In my mind, his offer to borrow his laptop was a way to keep me around so when I declined, he realised how serious I was about keeping my distance from him and he got upset. I responded to the message he sent about taking a hint and he ignored me. Then I messaged him a week later to ask him a question and he ignored me but the next day I saw him hitch hiking (we live on an island) and I offered him a ride to work and he accepted it. We spoke on the way there and everything was civil but my question is, why is he mad at me? Is he really upset because of the laptop or because I really showed that I dont want to talk to him anymore?
