Why

Why do I still think about alicia from time to time in the wee dark hours in the morning?  Why does some deep dark part of me still yearn for her arms?  She betrayed me, cheated on me and got herself pregnant.  All that I could have forgiven, but the lying I could not forgive.   She just could not handle me honestly, ever nor could she even show me any ounce of passion when someone was looking.   So, explain to me why I still want her when I have t'keya?  It doesn't make any sense at all...
