OMG I'm in that exact situation too. I'm sorry but I came on this question expecting an answer to help ME.
"I know you like me" If you like him too why don't you ask him out? You would have nothing to lose if he really does like you.
you ask her out, or show him/her that you like them
just tell her you like her and then ask if she wants to go out with you, but don't pressure her. Ask somone that is really good at telling if someone is flirting, and have them hang around the two of you, secretly though.
If you like someone, and they already may think you like them, just tell them that you really, seriously like them ask a friend 2 ask them out
Send them a valentine. Be nice to them, and when you think they like you, ask them out; it's not that hard really! I should know! ;)
Plead the 5th
Not really
Don't worry if you really like him and he really like's you there's no reason to be worry just go and ask him.
ask him to go to a movie he may be interested in
It really depends on how you ask it. You might do better to ask about their nationality or something like that.
ask them its the only way to really know if they like you
ask him when your alone
