yes
if its okay with you having your crush know you like them than yes.
yea it is more than okay
no nick has a crush on miley Cyrus it came on okay magazine.
No it is not okay.
no, thats bad
It is okay to have a crush on your cousin but it is a little awkward to be in love/have a crush on your 1st or 2nd cousin in my opinion
Yes, it is perfectly fine to be best friends with your crush even if they are already taken.
okay this is weird but nate has a crush on jenny
I think it is unlees he gets taller than you
No that is not okay. The fact that he is married should make you forget your crush on him.
Okay, I think I followed this; yes, if your crush's friend is asking you if you like your crush. YOUR CRUSH IS DESPERATE! otherwise he/she would probably try to keep cool and find out themself. I think this means your crush likes you.
Oh yes, you can have as many crushes as you like.
