I like my teenage student very much and she always smiles at me during the class time..and i can't help. ?

During One of the Grammar class when i said my all the students to use the preposition,''jealous of'' in words and i said them to write the sentence''she is jealous of my dress'',a teenage student of mine quickly responded as''i don't care''(facing towards her friend).Does she like me?i have made her already known that i like her very much.
