Hey buddy ! Sorry this happened. You very well may have been drugged. While it makes sense for your gf to be upset, if she has a sense of empathy / compassion, that should be sufficient within the context of this incident to not destroy the relationship. She probably needs some time. Because as everyone else is saying, there also needs to be some room for her to understand that you may have been drugged, and to be concerned about your well-being

Tbh, I have seen a lot of shitty social attitudes in relation to alcohol. You’re expected to drink, really heavily sometimes, and still manage to “handle your alcohol” ….. but tbh the effects of alcohol can easily go haywire, depending on the person. Feeling sickly beforehand / not eating enough / having things on your mind / the type of alcohol you’re drinking etc. etc. etc. can make anyone “lose it” from time to time. It’s sort of a gamble in terms of who you are and where you’re at in terms of your physiology at any given time. Alcohol is a drug, and it will never not be, no matter how socially acceptable its consumption is. So, even if you weren’t drugged, these things happen. It sucks, but it happens. Take it easy ! Hope everything pans back out. You can always message her friends and apologize. Everyone has had moments where they acted in ways that didn’t reflect who they really are, alcohol / drugs involved or not
