Why

Why do I miss you so much when you don't?
Why did I open myself up to you when you didn't even care?
Why did I care for you when all you were looking for was a good time?
Why do I still crave for a mail from you when I know you will not respond?
Why do I shed my tears for someone who has done nothing but hurt me?
Why did I think that maybe this could go somewhere while all the time you were married?
Why do I still want to trust when you were not honest about your marital status?
Why do I care even now when I know I don't want a guy who cannot take pride in his relationship with me?
