I’m really sad/ annoyed

So it was my boyfriends Christmas party tonight and I was like just drink 2-4 cola rum tonight because I want a consenting boyfriend tonight and he was like okay I can do that for you. (By consenting boyfriend I mean I want him sober so I can have consent to have sex with him because I got new lingerie and wanted to show him) also he started drinking at 3pm and we weren’t gonna be home till after 8. So fast forward to now it’s 10:30 and we’ve been home since 10pm and he is so sick. He is vomiting everywhere as well as the car while driving home which was scary I’ve never had a drunk person in the car when driving let alone vomiting. I was so scared because I was afraid he was going to choke. I had to put him in the recovery position because he was gonna vomit on his back.

So we’re home now and his mum is now helping me take care of him but I’m just so scared and terrified from the event. I know this may be a usual to some people but to me I’ve never had to deal with this and its the first time seeing my boyfriend drunk. He promised me he would not drink too much but I saw him drink more and more. I told him to stop but his friends kept giving him more untill I got shitty and started getting forceful and putting only a glass of water in hands reach because at that point he didn’t know the difference. I tried to get his friends to stop but didn’t want to be known as the girl who stopped his guy from having fun.

It was also the first time I had met his co workers and I didn’t want to make a bad impression. But now I’m blaming myself for causing this. I’m not sure of how I could’ve changed the situation. I’m just so shaken up and just want to cry i feel like this is all my fault.
