Girlfriend Problems, Blah

So my girlfriend drinks, drinks often, and drinks a lot. I'm not an alcoholic, although I do have a few beers here and there. For the most part, I prefer my sobriety for the most part. This has been causing problems with our relationship as of recent due to the fact that she will quite often get belligerent and then say something uncalled for and out of line. My response is to distance myself from what is potentially a disaster waiting to unfold. Most recently, we had a phone conversation that didn't end well and as a result, I have not talked to her recently. She has sent me a text message apologizing for the conversation we had and I have yet to respond. I'm not sure that I will. My life is great for the most part and I don't care for such drama. Back to the simple life I guess.
