How far & near

How much near can a friend come
Is there any rule or frame
I am talking about friend, not life partner
Can he or she become a family member
I know the answers
Yes, friend can be anything.

But I am talking about best friend
I am not her best friend
But she is best of mine
I remember her face all time
I have time for her always
Seems to not having for mine.

May be I could stay around her
But now thinking
It would be good if I go far
She did not feel to spare
Some words, some times, some joy, some sad
To keep me of her near.

I miss you and love you dear
But you do not feel me and love me
I do not beg to god on my knee
To make you understood
