Yes, I guess it's normal as some people just leave a lasting impression on you. Always seems like the first person you ever fell for seems to remain in your heart. You'll meet someone st your new school in time and he will fade away but there will always be a little part of him with you for years to come. It's normal. You're fine.
At the end of grade 7 (I was 12), I fell for this guy, then we went off to different high schools the year later. I'm in grade 9 now, and I still think about him and feel the same way i did the last time I saw him, in grade 7. Is this normal?
Called Infatuation, you're still in like with a dream. A dream of what could have been concocted with help of your imagination. This is because you two never had a real relationship but unfortunately you may meet some one else and he will fade away but then there is a reason none of us gets to see our future so there is always the possibility that this dream could come true.
Believe hard enough and any dream could come true. Good luck
