Is AUTHOR wrong in the post ? POST : Using my old account for this (also please excuse my poor english, since it’s not my native language).
(I should say that we are 25-30 years old).

My and the bf were invited to a small party at new years by his old high school friend (lets call her Tina) . It would be more of a formal thing, than full on house party.
It sounded perfect as i’m not a big drinker and don’t like going out that much.

My oldest friend (Let’s call her Jess) called me up and said that she had nothing to do on new years, and i felt bad for her. I said I would ask Tina if she could come, and she could.
On NY jess called me and said she had invited over our old friend (lets call her Laura) and lauras bf (Matt).
I had never met Matt, but I knew that Laura was a bit of a drinker. 
Jess said I should ask Tina if they also could come.
I felt a bit stuck. Both Jess and Laura are very old and good friends of mine, but Laura is a horrible drunk and will drag other people down with her
I told jess that this would be a small and formal party and that they would have to control their alcohol. Jess told me that everything would be fine.
I asked Tina and she once again told me that it was okey.

To be clear, Tina has never met Jess and Laura, and I had never met this Matt guy. But I hoped for the best.

Fast forward to the party, everyone is having fun and talking. A bit of alcohol is served, but everyone is talking it slow and we have a great dinner.
I get a call from Jess who tells me she, Laura and Matt are on the way. I get a bit worried as I can tell on her voice that they have been drinking quite a bit. I asked her how she was feeling and she just blurs out that ”IT’S NEW YEAR GUUURL, EVERYONE SHOULD BE DRUNK, WE ARE BRINGING THE PARTY B*TCHES”.
I start to panic and tell my bf that they sound waaaay to drunk to fit in. He tells me not to worrie yet, and wait until they arrive.

What follows is me having to babysit 3 grown people as they come in, put up 3 full bottles of alcohol on the table, make themselfs more drinks and are loud and obnoxious. They spill on the floor, on the carpet, scream and almost brake all of Tinas wineglasses, and Laura and Matt start to argue. 
They have not even been at the party for an hour befors Tina comes up to me and tells me that my friends has to leave.
At this point I am so embarrassed that I wanna die, and i tell them to leave.
It takes a solid 30 minutes before they go, and Matt startes to say how I’m a bad friend for throwing them out from a party on new years eve, and I should expect people to get a bit drunk.
They leave and i can do nothing but dit and stare as my bf comfortes me. 

The next day (today) my friend told me that she was so mad at me for throwing her out, and she would never do that to me. I was the worst person for not taking care of her when she needed me.
I told her that it wasn’t my party and not up to me, but she said that I should be on her side, sinne we are friends. 

I have been beating myself up for this all day, I don’t know if I did the right thing..
