Forbidden yet allowed

I so desperately crave everything about you
Even things you don't notice you do.
I'm so scared and apprehensive for i know this brings tears
Falling for you may not have been a mistake yet still one of my fears.
Because i cannot have you and we change in many ways.
The friendship so strong lost in a few days.
So happy one minute for i know how you feel
Then ripped from the inside as i learn they cant be real.
Tears fill inside my eyes as heart yearns
Because i come to see the truth my heart burns.
So happy and sad at the same time, feeling so lost never to be found
For how can a relationship be forbidden yet allowed.
