When the OP refused to use the drug, a lengthy argument ensued lasting about half an hour. Following the refusal, the OP chose to leave and go home, which has resulted in Aldena being upset and complaining about the abrupt departure. The OP is now questioning whether his reaction was appropriate and is asking if he was the jerk in this situation.

My girlfriend, let’s call them Aldena, told me last night that I was a pussy and didn’t know how to have a good time. I said I did, and Aldena says something along the lines of “Then do a line of cocaine right now.” They then proceeded to pull a bag out of the couch cushions and set up a line on the coffee table.
We argued back and forth for about 30 minutes before I got up and went home. They are upset at me and complaining that I left abruptly. AITA?
Conclusion
The central conflict revolves around the OP’s refusal to engage in illegal drug use when pressured by his partner, which led to him leaving the situation. Aldena is focusing her frustration on the OP’s choice to exit the interaction rather than on the initial demand for drug use.
The core debate is whether prioritizing personal safety and boundaries by leaving a situation involving illegal drug pressure justifies the partner’s subsequent emotional reaction. Readers must decide if the OP’s departure was an overreaction or a necessary act of self-preservation against coercive behavior.
Here’s how people reacted:
If you smoke dope you’ll just become a worthless lazy fvck…
Just the same, DON’T DO DRUGS.
And brother, if you leave her now nobody would blame you. That’s a mine field of red flags. Stick up for what you believe, that shit can ruin you. Much respect.
Also from me personally, I wouldn’t exactly call you an asshole if you called the police on her for possession.
you’re still too young to be fucking up your body so bad , and more so to impress some high school fuckers,
bro you wont even remember these asses when you’re 25 and onwards
She’s your gateway to addiction, trauma and abuse.
Time to find a gf that doesn’t think drugs are cool, especially drugs at your age and drugs like cocaine.
Good luck
That girl is spiraling down fast and she wants to take you down with her. Dump her and find a new friend group.
