<human>: Started dating this girl 4 months ago, liked her for awhile, shes like me for a very long time also. Things are great. Very much in love, I stay over at hers frequently and its fantiastic. 

However she does coke occasionally. I find that super unattractive,  She knows I dont like it, and has promised to cut back/stop eventually. She also wont do it if I'm with her, knowing it bums me out to see it. Honestly though I know she does most weekends. She doesnt tell me, but its super obvious when she calls me at 5 am wanting to come over cause she cant sleep. Just looking for anyone with a similar experience to give some advice. 

I had a serious talk with her post New Years about it, and she promised she would dial it back.... but shes partied at least once every weekend since. It just really bums me out cause I love this girl and I know some people who go light on the coke in the early 20s and years later they're still doin it and regretting the shit. I also realize how fucking hard it must be to go hang out with your friends, have it around, and not join in. It's not like it has had an effect on our relationship other than me being stressed. It's also her life and I cant just make demands. Anyone have experience with coke and a relationship before?

Can you condense the text into three sentences or less?
