<human>: This saturday we celebrated our 3 years together. We couldn't be together because i had to work untill 3 am, and she had to work during the day. 

A little background. I took drugs when i was 18 untill 20, weekly, i have lots of friends who do it on a weekly basis. I completly stopped, because it's nothing for me, it was a phase in my life. My gf never took any and is always telling me how trashy she thinks it is, and it fucks up your brain, always the first one to comment on it.

She telling me yesterday that she took 1/4 of an xtc tablet came as a complete  sursprise for me. Ok, it's nothing, 1/4, and I honestly don't care that she took that, or even more, she's allowed to do what she wants, but it's the way she always talks about it and still does it, that makes me feel bad. 

I reacted wrong, i was not mad, but i made her feel guilty. By not believing her she would never do it again (everybody who takes drugs says that.) and so comparing her to some fucked up friends of mine. 

I called her today telling her i'm sorry for the way i reacted, and that i don't care what she does, but that i was shocked to find out, and thus react like that. 

Now, she's cold towards me. 
I feel like she lost a lot of value. 
I'm not sure how to react.
I'm not sure if I want to continue with her, altough that seems hard.

What's your opinion on my situation reddit?

Can you provide a brief rundown of the text in within 3 sentences?
