Complicated multi-layered question
first everyone is an individual
not all "girls" are the same
second if you are "arguing" you have lost control of yourself and the conversation
the chances working through issues/problems/questions with an argument.. are terribly bad
(unless you are using the more technical definition of argument for debating)
let's start witht he basics How to talk communicate here was a good link
it applies to work place
but would be helpful in a relationship.

then there is listening, which requires serious effort!

note I am in No way promoting the website I have linked twice it just happened to have good summery and application.
okay now you can form ideas well in talking and are learning to listen better
next is the part that is NOT taught ...
learning yourself and her and each other!!!
you change .. today was a "good" day or "bad" day... there is this issue at work or home
today you are doing dishes and you break one... it is called LIFE
girls (and guys) change all the time we learn, adapt
one of the Key things from my marriage is By the time you figure out what is going on with your partner , chances are something else has happened! and they are now dealing with a "new" thing!
relationship is a growing thing it changes, moves, shifts, even jumps to new places
the way to "win" is to embrace both your life and the person or persons life as well
how much you incoperate them, depends on if they are a casual aquantance, friend, or lover!
Best of luck!
if you have specific issues I will do my brest to assist but in life YOU are the one that affects and effects
