Is it normal to see one of my teachers as a father figure?

So I will start at the beginning of the year. When I first saw my schedule, I was terrified that I had this teacher. All I knew about him was that he had a reputation for being mean to students. A month into school, he still mortified me and I did not like him one bit. Now, he is my favorite teacher and I love having him as one of my teachers. From trying to hit kids with doors in the halls, to making sarcastic comments during class, he never fails to make my day so much better. I get happier when I see him in the mornings, knowing that he is at school that day. I do not normally talk in his class, because it is pretty much just him talking and us taking notes every day, so I don't usually put in my input unless he directly asks me a question.

Anyways, in the past month or so, I have noticed that I have feelings for him as if he were my father. So I guess you could say that I love him like a father. Which is a weird thing to admit to myself. I mean, he is my teacher. It is a strange thing to grasp. I have my dad at home,(my parents are separated, mom lives in a separate state, which I am okay with) but we have never really connected well. I don't enjoy being around him or talking to him, really. He goes to work, my brother and I go to school, then we all stay in our rooms when we get home, occasionally coming out to do laundry or eat or something.

Going back to the teacher, I mentioned before that he is known for being "mean" to students and making fun of them, in a playful way, I guess. He is just very sarcastic. He has never once been mean to me in the slightest. Everyone else in my class, he has playfully belittled in some way, but never me. If I am the last one to finish copying something down from the board, he patiently waits for me to finish before going on. With other people, you can expect him to say something along the lines of, "Can you hurry up? The rest of us would like to actually get somewhere today." All of my teachers are kind to me because I am the quiet one, but he seems to make a little more effort than my other teachers.

I also strive to make him proud of me. He is known for his difficult tests, which I was making kinda bad grades on in the first semester. Then I got a very good grade on the first one of the second semester. He stopped me in the hallway the next morning to congratulate me, and it made me really happy. Since then I have been working really hard to try and get a 100 on one of his tests. I am yet to do that, but I always try to get 100s on all of the homework assignments in between tests.

I want to make him proud more than I want to make my own father proud, and I may love him more than I love my father. I know how extreme that sounds, trust me I know, but I always think about how his family is SO lucky to have him there for them. I used to cry every morning at the beginning of the year because I wouldn't want to go (bullying), but now I love going because of him(and because of my two close friends) and school is the highlight of my day. I am miserable over weekends because I am stuck at home without school, and I miss my teacher constantly. That part sounds kinda unhealthy...but I have heard many kids that miss their teachers over weekends.

So that was extremely long. Sorry about that, and thank you so much if you actually read it all the way through. I just want to know if these feelings are okay...I am not planning on acting on them. I WOULD like to talk to him more, since I only really talk to him if I am in the hallway with my friends, but I don't plan on ever telling him how I feel and about all these "emotional issues" going on in my life. I think it is just because I feel like I am lacking a father figure, and I am with my teacher every week day so he fills that spot.
