Do i love my teacher? or is just a crush?

i graduated from middle school n i cant ever stop thinking about my homeroom teacher whose also my math teacher....and also science....every time i see him he gives me erflies i some times have ual feelings for him but its more like i'm in love with him or something its a really deep feeling. and at the last day of school he gave me the most warmest hug i have ever got from anyone...i cried for him when i left middle school..n i liked him for like 2 years already people say that its a crush n it will go away in like a few months but it hasnt n i was just wondering is this a crush or am i inlove with him????? btw i had never done anything that would get him in trouble i just act like a normal student cause i dont want to lose him...
