Is it normal to be close to your teacher and treat her as your mom?

Well, we known each other for almost 3 years already.. We became close and she became my mom in school. She is the one who makes me feel that I can do everything I wanted to do. She motivates me to be the best I can. She agreed to be my mom in school.. And there are times that (I think) she got jealous of her co-teacher because I was with them.. I love her so much.. But I think, she don't give back the love as well.. Sometimes I think that she don't want me anymore. She became aloof with me recently.. I just don't know why.. I think that it is not normal for me to do that since I'm already in 3rd year college. I know I'm just finding a mother figure and someone to share my thoughts to.. Hope you could help me figure out if its normal or not. Hope there will be someone who shares the same feeling like mine.. :)
