I Don't Know What I Did ...

Hello! I am a girl almost 17 years old and I want to ask you for help. Some time ago I liked a boy very much. Gradually my feelings intensified. The strangest thing is that at first he didn't know that I existed ... Then we met through mutual friends. I went with a friend almost every day to the place where in principle he goes out, and it is quite far. I went hoping to see him because I was ruined every day. I know it sounds psychopathic to chase someone like that, but I don't know what happened either ... When I got drunk I called him from hidden numbers and didn't tell him who I was. I congratulated him on his birthday, but he didn't answer me, he hadn't answered anyone at all. And one night I called him again and he said if I wanted to see him the next day, I told him well. The next day I went to the place we had agreed. I was so worried, yet he has no idea who he's dating. Then he came and we went for a walk, he was very nice. He told me that I just had to tell him without doing such childish performances. We talked for about an hour and he had to leave because he was at work. He said he didn't want relationships at all because he didn't have any time. After all, he goes to school, work, and has a small dog. And he apologized to me for seeing so little and for not answering my birthday and said that when he was resting he would call or write to see me again for more time. Well, now I don't know what to do because my son on Facebook, however, didn't answer or write to me. Vee was still interested in me finding my profile. What did I do ... should I have gone to him, I don't know what I am now in his eyes. So my question is, if he doesn't look for me, what does it mean? Or if he doesn't look for me, should I look for him? Have I fallen too low to have admitted my feelings?
