Depends what your situation is.
Friend Groups?
Distance?
Appearance?
if you like the guy, lead him on and hopefully he will like you.
Move on find another guy
Get him to know how you feel. Then he will understand and you may have a chance to get him to like you.
(from a guy) You should probably lay down the charm but don't act like you're desperate or too easy. Just flirt and try to be really nice and sweet; say "Hi" to him anytime you get a chance. But like I said don't do it so hard it will seem like your desperate or too easy.
i would pick the guy your not going out with take a chance with him.
Maybe he wants to seem like the tough to get guy in school? If he does like you then, well, ask him.
you have to choose whats more important this guy or the chance of losing or friendship?
Does he seem interested in interacting with you? Does he seem to look at you during class/passing periods?
no.
If a guy is loud around you, it could mean that he is trying to get your attention or show off in some way. He might be trying to seem confident or outgoing in your presence. Alternatively, he may just have a naturally loud personality.
Honestly, not the kind of guy that's good to be with. A guy that likes a fight and doesn't care if you get hurt doesn't seem like the right guy.
If you don't tell him, he has no chance to respond. But, nobody here knows you or him, so it has to be your decision.
