Is it normal that i'm very attracted to my teacher?

I am a younger girl who, I suppose, has a thing for her teacher. I grew up in a very dysfunctional household where my father was never truly there for me, and pretty much every other male figure in my life has either abused me or failed me in some way or another. At school, I'm very lonely. I don't eat lunch with other kids, I'll instead just hide somewhere at school and study. This teacher knew I was lonely, and I don't know how it happened, but I soon began hanging out in his classroom during lunch and even after school. I also don't know how, but he always knew whenever I was having a bad day, and he CARED. He asked me how I was doing, and talked me through it. He would know I was lying when I said I was 'fine'. I can't even tell you how many times I cried in his classroom. His personality is also extremely similar to mine, we are both very sarcastic and have a very dry sense of humor. We both have a very strong dislike for most people, so in a way, we bonded over that. I could best relate him to Severus Snape from Harry Potter.
Anyway, I'm not entirely sure how I see him. In some ways, he's like the father I never had. In other ways, he's like a caring brother, or even a therapist. He's my best friend, and probably the one person in this world that I do trust, at least at the moment.
Sadly, it's summer now, and he's moving to another state so I won't be able to see him again. I'd be lying if I said this was easy for me. Anyway, I know this whole situation sounds totally bizarre. I'm just wondering if this is just some deep 'daddy issues' making their appearance, or what. Any input would be appreciated.
