<human>: Provide a brief overview of the text.

So here's the scoop: My gf, lets call her D, turned 21 over the weekend. So on friday us and another couple went out to a hockey game and had a great time. Things were excellent as they always are. So on sat night I knew she wanted to go out and do the bar thing which is cool cus I know that she isnt able to do it. (I'm irish, all my family lives there and only we live in USA so I've been doing the pub thing since I was young and have done the whole bar thing) So I drop her off with her friends and agree to pick her up no problem. SHE GETS FUCKING DRUNK. like i've seen drunk but she was drunker. D was sick from when I picked her up at 1:30 till 4 then 6-7 then woke at 9 not remembering anything and puked all day too. So yea I was like ok she was given a lot of drinks, prolly could have said no but whatever. D was hungover all the next day and felt like shit on monday too. So she wants to go out to this popular campus bar tonight with friends, some of which are mutual, girlfriends and on guy that I know. I'm totally fine with it, I just cant go out cus thats the law here. I trust her completely but I'm afraid she is gonna get trashed again. Also the bar is pretty much one big dance floor and is notorious for having cheap drinks so its easy to get drunk. I'm just sorta worried I guess and pissed that I cant go out with them. Also she is a chem engr student like me and has an 8:30 on fridays. I want her to go out for the thrill of being able to go out and have fun with her girlfriends but I just feel weird.
<bot>: My girlfriend is 21 and I'm not and I'm worried about her going out and getting drunk without me there. I trust her but I'm just worried I guess.
