It is a real rough situation, in which you find yourself Weiser.

There are various severities of bi-polar, and the manic mood might now be the mood she is in. People in such moods have a lot of energy, are a lot less inhibited, need less sleep, feel like they can take on the world. The lack of inhibition can lead to a lot of problems.
Of course, the manic mood does not last forever, and the mood can change to the almost complete opposite: extremely exhausted (need lots of sleep), lack of energy, etc. Which can be very draining for the people around her.

Not all cases of bi-polar are very severe (there are various categories, but I won't bore you with that). In general, the better a person is able to handle him/herself properly and hide the illness, the less severe it is.

What is important, is that she gets help, and stops drinking (and partying, on the scale she used to). If most of her friends do not see the importance of that for her, then it will be extremely tough on her. Because then all kinds of social pressure start working against her.

There might be other issues (like setting realistic goals and targets), but the same applies: she needs a healthy environment in which the behaviors that cause a lot of problems, are effectively combatted, so that she will have a better life.

To be honest, I am a bit surprised by the recommendation to break of the relationship if it did not exist that long. What counts is the quality of the relationship, the influence a person has on the bi-polar person. Granted, bi-polar people are not the easiest to be around, as moods can fluctuate between elated and depressed, and meds do not suppress bi-polar completely. It takes quite a bit to be able to handle that.

You can always try to be there for her. I know, whatever you do, it will be hard on you as well. But if she does indeed go to AA, does indeed make a serious effort with her issues, I don't see this as preventing a good relationship being created. However, you can't make yourself 100% responsible for her.

My suggestion would be to be a bit of support, which she will need. If you expect her to lose all her friends because of this, then that will affect her adversely as well. If she does indeed fight the bi-polar succesfully, it barely is an issue. If not, then she will be extremely hard to be around, and ultimately you will cut her loose completely.
