<human>: Hey so, I'm on mobile so I'm going to keep this short. 

Last night we were a bit tipsy and telling each other the truth about any lie we've told. I told him I lied about how many people I had been with and he was fine, if not a bit hurt that I had lied. 

Then he dropped the "well, I did cocaine while on vacation in June...."

I asked him if he was joking and he said no. 

I was pissed. He knows my families history and how I feel about that and he expects me to just be okay with it. And be okay with him going next year, but we haven't discussed if he'll do it again. 

I asked him why and he said he just wanted to try it. 

I don't trust him to not want to try other hard stuff now too. 

He said he doesn't want to try anything else, but I keep thinking what if it was offered like cocaine?

I'm at a loss reddit. What do I do?

Summarize the given text in a few sentences.
<bot>: boyfriend did cocaine while on vacation. Just expects me to be okay with it after knowing my families history with drug abuse and how uncomfortable they make me. I'm pissed and don't know what to do....
