Why I am missing her??

Why I am missing her.???
 when she is not with me..
Even we are not in contact since a year... Don't know where she is ?? what she is doing now??
nothing at all... but somewhere ...sometimes...somehow..I miss her...not only at my lonely times but misses her at the times also when I used to be my best buddies with whom I enjoys a lot..
we both together had hard times...many many many misunderstanding.. but then also...
Missing her badly...
Missing her badly...

But life moves on and on and on,...
