Though it seems your future is already decided for you.. another tip of advice when you're trying to win someone over- the whole "you do it too" business isn't going to help your situation at all..
I know as men we consider ourselves more logical than women in some things, which may or may not be true ( no need to open a debate here ). But my experience with women tells me that the "you do it too" thing just doesn't stand. However you word it - whether its politely or angrily it just doesn't get through.
An example:
Girlfriend does something that may bother me slightly.. can't think of an example but something stupid and meaningless.. I let it slide.. keep things going.. bottle it up.
I make the same mistake.. girlfriend goes mental.. "when did you stop caring? are you serious?? blablaba"
As a logical person, I say.. "honey, you did the exact same thing" - I list the whereabouts and frequency of this event.
Girlfriend gets even more furious - You lose even more points.

Kind of stepped away from the point here but this has happened in every relationship I've been in..
