Is this being rude?

I (26f) agreed to date this guy (28m) I often meet at the library even tho I really wasn't into him. I wanted to decide whether or not I liked him after I spoke to him.

Anyway, I'm really talkative so the first date went for 3hrs ( I didn't discuss anything personal tho), but I noticed that he was becoming alittle too clingy after that. He'd text me a lot and I began feeling exhausted with it. I felt I didn't have a break, so I asked him to slow down the texting but he'd get upset. At one point I decided to tell him there was a lot going on at the moment and I just needed a break, but he wasn't ready to listen. He started getting mad at me and said I'd led him on sinve the 3hr date was too long.
