If you want to know if he likes you I'd subjest you go talk to him and see how he acts when he's talking to you. Most people will give off signs that they like you with really deep eye contact in an certain way and flirty smiles. It's pretty obvious most of the time.
As for a spell. Casting a spell on a person to "make" them do anything is controlling there will and that's never a good thing. Most spells influence strongly, but it's never a guarantee that they'll act on those emotions..it really depends on there own will power and there ability to resist. Plus it often is only temporary and can cause problems down the line. There are spells to make you more desirable which could catch his eye. I would subjest you look into those types of spells.
