I don't get it????????????

This senior guy in high school that goes to my church followed me on twitter and he has been replying to some of my tweets. Then, he saw me once at church again, and when I got home he asked me for my number, so I gave it to him and we started texting each other. He was flirting with me a lot and he practically texted all day. He said I was very attractive, one of the most prettiest and good looking girls at church , and he said he loved my eyes, hair, smile, everything haha.. He always complemented me and said I was really pretty; he was so sweet lol. Anyway, we got to know each other more, and he always sent me good morning texts which I really liked lol. But by the way, when we first started talking, I told him I was a freshman, and he thought I was a junior.. Anyway, we were still talking for days and he wanted to see me at church one Sunday, and he said that he dressed up all nice for me, which I thought was so sweet lol. On to the point; so obviously this guy was really interested in me, and I think he was thinking about going out with me. We kept talking and talking for weeks and it was a pretty good flirty friendship between me and him. So, I guess I started to like him, and obviously he liked me. However, when I saw him for the first time after we talked for a while (we didn't see each other in like 2 weeks) we had a good convo, but when I got home, I texted him.. But he didn't answer.. So I continued to send him text messages (they were not desperate text messages) he still didn't answer.. I kept doing this for a few days until I gave up .. After a week I asked him if he got sick of me or something , and he answered me and said "you're just too young." And I was like "then why all the flirting and talking to me all the time?" And he replied by saying, "I didn't know you were a freshman.. It wouldn't work out anyway cause I'm going off to college." But that's weird because I thought I told him I was a freshman when we first started talking. I'm so confused.
