LTR has been acting up recently. We've been together for roughly six months, but now that we are back at school, she has been an emotional wreck (stressed about internship, school, etc.). This past week in particular, I've noticed that she has issues controlling her alcohol intake.

Saturday, she drank too much and passed out before we had a chance to go out together. Tonight, she drank a significant amount at a work event, and then drank more when we met up at a bar, to the point where she was slurring her words and stumbling. I took her back to my place, and she proceeded to get angry over nothing and kept repeating how she was just going to go home. I calmly replied that I wasn't going to stop her, to which she said she wished "I would just pay attention to her more." I did not reply and held eye contact, but she ended up leaving anyway.

Overall, she's been pretty good -- low partner count, submissive, feminine, and we've had good times together. But she's been consistently disrespectful: I've held frame and told her I won't tolerate it, and tonight I exemplified that by not reacting to her and letting her leave. My question is, how much leeway should I give her? I understand LTR's require a mixture of Alpha and Beta traits, but I cannot figure out what to do in this situation.
