it must b tht time!!??

why does the honeymoon stage in a relationship have to end? why cant it be the honeymoon stage all the time or not at all? why do guy/girls send each other mixed signals? why do we fall for them? why do people cheat? why do people lie? why can i walk away from a relationship and not feel an ounce of pain or regret? why do people hate? why do people fall in love? why do people fall OUT of love?
