I'm 20 year old male. I have never had a girlfriend. I take good care of myself and workout. I have heard I'm a good looking guy. There is this hot zumba instructor in my gym. I don't have a crush on her , but I want her to think I'm good looking ( maybe it boosts my ego ). Even she is 20 , she teaches zumba and goes to college. She has a boyfriend of 8 years still going. I don't know why , but I assume she hates me. During class , she smiles at people a lot , but she doesn't smile at me that much maybe because I'm serious and don't smile also. I know there is no way she will be attracted to me because she is in a relationship for 8 years .She looks at me more than anyone else in the gym. During class I told her to switch off the fan , she told she will but I think she forgot. After class got over I smiled( she didn't smile but came over) at her and she said I'm sorry I didn't switch off the fan , because there is only one switch that switches off all fans and it would be very hot. I said I felt cold because I was near the air conditioner and the fan and she said you should go to the other side. Then I said it would be too hot and she laughed a little. By the way , we both were in the same tuition in 8th grade and when my mom introduced me to her , she said she didn't remember. This was before all this happened. We are not close at all because we barely speak and I never approach. When she doesn't smile , I think she hates me . She is with same guy for 8 years.
