she is my friend

hi! see you again guys :))
now i want to tell about my friend.
i have four bestfriends in my school, one of them are closest with me.
i always tell her about one person i love.
and a one day...
someone i love is ask about my friend, him ask how many phone numbers of her..
then i told, his number is blablabla...
a little jealousy in my heart :(
but her is my friend, and him is one person ilove..
I should not be so negative about them. 
But...
