why is it so complicated?

i want to tell her....but i kow she wouldn´t understand so every time i try, i shut my mouth so i´m sad and don´t know what to do....
she always tell how much she loves this boy and she thinks he has a girlfriend.....it hurts...it really really hurts
and she didn´t get it...i´m a bit depri now and she always asks why...what should i say? that i´m in fucking love with her?
i can´t ´cause than she would be like " what? you´re crazy! you know i´m not in love with girls! go away!".....mh yeah and that´s why i just sit here, depri and tell you my problems....
