Answer:
there is really no right answer to this. if you really want to tell him, tell him, but there is no telling what he will say or do. if he makes fun of you, then you can find someone way better than him.
Good Luck!
I have one suggestion try and figure out if he likes u there will be different signs
1. He will start talking to u more
2. He will most likely ask people what u like
3. He will surprise u with gifts (only if he really likes you)
4. Well if he likes u he will ask if u like him or 'would u like to be my girlfriend'
Well if there r some or any of these signs you should ask if he laughs find someone better than him who apreciates you for who you are.
