You ask her out
He/she wouldve already hinted that they liked you. Do they look at you Alot? Do they talk to you or try to impress you ? Those are hints you should take if you think your crush likes you.
ask them out...
as hard as it is, you have to, he's not worth it.
Ask him if he likes u, and if he denies it tell him u have a crush on him and see if he says he likes u.
Bring up your crush in conversation. Start talking about someone your think also likes him/her. Then say "you remember when I said that --- likes that guy/girl? I like them too" it should work.
say what u feel
In my opinion, I think you should dress like Sandra Dee and start breaking out into song!I will say just be your self and if he still doesn't fancy you get yourself another crush who likes you and fancy you
depends on if you know he likes you or not
Not too intimately.
You should go for it if you know that person likes you go for it no holding back.
No, wait for him. Speaking of, will you be my girlfriend?
Nothing should come betwenn friendship. You need to talk to him/her and sort out what is going on. A crush is nothing to fight over.
