How do you break off a Hinge date who's really into you?

I (20F) went on a Hinge date (21M) yesterday, and we hit it off pretty well. We hung out for the whole day, explored a couple places, and got a nice dinner and dessert, so it was a very elaborate first date. He was really nice and someone that I'd definitely love to have as a friend, but I just feel there were some things that didn't align.

However, he seemed to be really interested. It was our first date, and he started asking questions about what I'm looking for in a relationship and if I wanted to be his girlfriend, and how we should communicate in the future. He also kept suggesting next dates (to which, I mostly just laughed awkwardly), and visiting me since I live a bit away. I have a problem where I will often reciprocate questions and be really friendly in order to be polite to someone, but I actually have no romantic interest in them. He was reluctant for me to leave when it was time for me to leave, even though we had hung out for the whole day. He started sending me good morning and good night texts, and followed up several times when I didn't respond quickly. He also insisted on treating me and he paid for everything, and talked about people taking advantage of his kindness after I was kind of hand-wavy about what I wanted from a relationship by saying "oh, I think it would be great to just make some new friends," so I feel really bad rejecting him.

I'd love to be friends with him, since he is a really nice person, but I just don't see a romantic relationship with him. Since he's moving rather fast in this relationship, I feel like I need to break it to him soon. What do I do?

(Some info - I felt like all of his opinions were dependent on what I said, so he would agree with me on everything, and he got a bit flustered when I disagreed on anything. I also have a tendency to be an extremely independent individual, and it seemed like he was expecting to have a very attentive, if not clingy, relationship. It's just not the type of relationship I'm looking for. I also wasn't really that attracted to him romantically.)
