Input: We're spending the day at her cousins for her 17th birthday and she asked her mom if she could have a beer, her mom said that she doesnt think its the best idea but gave her one anyways. Now ive (16) voiced my opinion very strongly to her on why im against underage drinking and smoking and i told her if she ever did anything like that i would get upset. A week from today we'll have been dating for a year. She decided to take the drink and after i while i asked her she could stop drinking it. She asked my why. I told her that i dont like it and its upsetting to me. After a while, this argument got to the point where she told me to just leave. I was shocked and a little hurt so i asked her why. She said i was ruining her party (close family) and if i was going to stay, i couldnt be upset with her. I told her that she knew it would upset me but she did it anyways. Thats when she told me that she doesnt care if she upsets me and that she really wants me to leave. I didnt really know what to say so i told her im sorry for ruining her party but she told me to leave anyways. So thats where this is now. Not really sure what to do so, am i the asshole? (reposted with title change, moble wouldnt let me change the title)
