How much should a guy text you after a first date?

So I went on a date with a guy from an app. This guy would not stop texting me. He would do it in the morning, afternoon and dinner. It has been 3 days. The thing is I told him in the beginning that I want to get to know him first. I didn't feel attracted to him on the first date. I thought he gave me friend vibe. I was thinking to go on 2nd date with him. But, I feel so fed up of his text right now. Can you guys please suggest me what should I do?
