Is he messing with me?

So we met 2 years ago at a camp where I live. We sorda clicked right away. Talked all the time ate together. We did everything together while we were there. The camp was only 14 days. When it was time to say good bye we acted like nothing was going to happen we were gong to call an write to each other and it was all going to be ok. I went to another camp after that and never was able to call him when I got home. He called when I got home and was mad I didn’t call him. We had never really talked about a relationship so that was the end. He lived to far away for us to have anything anyway. He emailed me before Christmas and we haven’t really stopped talking since. Then he told me he graduates this year. I’m 14 and he is 18!! My mom would flip if she found out that I liked an 18 year old. He calls me his boo his babe. I really like him and he is going off to college this summer and ill be a freshman in high school. He also said that he new I liked having a 17 year old boo. I said do you like having a 14 year old boo and he said your 14? I said yah. Then he said I could do that! I like having a younger girl friend! Did he ask me out? I just laughed and that was the end of that. Another time was today we didn’t have school today cuz it was too cold and windy. I told him that and I was home alone all day and he said I should have been there. I said yah you should have. Then I asked him what he ment by that and he didn’t answer me. What did he mean by that? Does he really like me? Is it a good idea for me to get “involved”? What do I do?
