what to do, what to do

I have a crush on this guy before. maybe it’s almost a month that I started hating him. it’s just that he’s annoying. it was like he needs attention from girls. so, I told my friends that I don’t like him that much anymore. but my other friend wants to know what he looks like so I took a picture of him yesterday morning since we have the same class. I think when I took it, it wasn’t that obvious ‘cause my friend thinks that it looks like I’m texting. but after that, I think he noticed that I took a picture of of the class which includes him. 5 minutes before the bell rings, he just raised his phone, pointing the camera lense on me, trying not to be obvious, I think, and his friend which is also my friend encourages him like “go” or somthin’. I really think that he took my picture. how will I know if the guy likes me or not without making any direct contacts with him…
