Need help! Any idea what she's up to?

I have a girlfriend who suddenly would not allow me to drink alcohol, I just think that it is a little unfair because she used to let me drink occasionally. Then there was an incident that i have to lie to her just to be able to join my friend in a Friday night out. After the said incident she suddenly allowed me to go out anytime and drink as much as alcohol as I could, she even told me to drink 'til death, and she promise that she will not be mad at me... Guys, what do you think? You have any idea what she's up to?
