After the first date

Yesterday I went on a first date with this guy I've known for awhile. He asked me, and after 3 times of him canceling on me, we went to see a movie and I had to pay for my own ticket. Before the movie started we had our first kiss and then he took a phone call and then during the beginning of the movie, he asked me to be his girlfriend while making out. I said no and as the date went on, he wanted to go further than first base and when I said I wasn't comfortable, he was really sweet about it. When I dropped him off, he said "okay bye" which I found odd because usually guys say things like "I had a good time" and "we should do this again sometime". Now it's the day after and he's snapchated me twice once saying "yo" and the other was just a picture of him. I haven't replied because I don't know what to say
