kinda watch if he is ever hold hands with another girl or flirting alot more then he would if she was just some girl....or you could always ask him or his friends....
You don't go there.
FIRST...be honest with the person you are currently seeing. To not tell him/her is selfish and cruel. SECOND...communicate with the person you think you like
Find someone else and stop seeing him.

they still like you and can't help getting jealous seeing you with someone new or you did something that made them mad
You don't. If he seems to like someone else, he does. Believe it or not, he is not the last guy on earth. You will find someone else, move on.
well bullies may think you know just because someone is kinda different from everyone else that they are kinda like seeing someone inhuman. Just my opinion.....
If he keeps in touch or initiates contact without needing or wanting anything from you is one way to tell. Also is he spending time with you. You can always ask him how he feels or if he is seeing someone else. Who is he seeing at lunch or weekends, if it's not you-find out if it's someone else.
If you smile when you are speaking about them to someone else.
You should probably look for someone else to like.
it means you think their hot. It means nothing about if you like them or not, anything is possible in your dreams.
It would probably be best not to tell your friend that you like him while he is dating someone else. If they break up, then would be the time to speak to him.
