Loves Shadow

Have you ever tried to get something that is close to you but failed terribly? Well that's how my story with my best friend is. His too close to me but far away to have for myself.
Being in love with my best friend has never been good with me. My heart, mind and body aches for him to be mine. He should be mine to to hold, love, care for and cherish for the rest of my life but that can only happen when he finally considers to be more than we are now and let me take over his mind, soul and body.
Should I just end this friendship and spare myself from this heartache? or should I continue being his so called best friend and keep hurting myself believing he will be mine soon.
Will my best friend ever change his mind and consider taking the next step of me being his girlfriend or maybe wife.
