When the love hormones start flowing. When the love juice starts flowing from a woman's brain, she will ignore almost all of a guys flaws and only see the good in him, and then automatically think he's the one, regardless of if they are even compatible or not.

Not really a set of steps or list of qualities that will make a woman love you. It's a process. A triggering of emotions and shared experiences, combined with euphoric lust and shared intimacy. It just kind of happens on it's own, from spending enough positive and exciting experiences with a woman.
