Letting go

Why it's so hard to let go someone that once became apart of you, eventhough only for awhile?

I keep on asking this question again&again, non-stop to myself. Because I'm in this situation. I can, but I just need some time. But I know I can't. How can I forget you when my other half is you? I should be strong to go through all these. I need a lot of strength to keep my head up high. I need you. I want you in my life. But I know, I can't. I just need to be patient and wait till the time comes. If God's will, you'll be mine again.

I miss you. You know who you are.
