So to recap:
* Be cool, bit cocky, act like you're hot and know it, don't flash your money but just act like you know you got it if you need it, just give off a good air of confidence. And heck, sometimes when you think she's starting to take you for granted --- start blowing her off sometimes. Or even abruptly end the call saying someone else is on the line. Things like that will tell her "hey, i ain't your doormat woman".
Key is --- be cocky, cool, a bit of a bad boy. And every now and then just SHOCK her with these little things of tenderness. Kinda like surprises. Go watch some 50's greaser movies on how guys used to "woo" women back in theri days with their suave debonaire.
But of course. Don't be a jerk. Have a good personality, but if her time spent with you is spent arguing, it'll never last (and who really wants to be with someone if it's tense and argumentative anyways).
