What is this I am going through tonight !!!

If I'm not in love with you,
                      What is this I'm going through tonight,
And if my heart is lying then,
                      What should I believe in;

Why do I go crazy,
                         Every time I think about you,
Why else do I want you like I do,
                        If I'm not in love with you;
And if I don't need your touch,
                       Why do I miss you so much tonight,
If it's just infatuation then,
                      Why is my heart is aching;

To hold you forever,
                       Give a part of me I thought I'd never,
Give again to some one I could lose,
                      If I am not in love with you;
Why in every fantasy, Do I feel your arms embracing me
Lover lost in sweet desire, why in dreams do I surrender lying with you;
             
Someone help explain this feeling,
                     Someone tell me If I'm not in love with you, what is this I'm going through tonight.....
