<human>: So I met my girlfriend in college. I was a couple years older than her so I graduated earlier and had to move to another state for my job. She stayed behind at our college town with all of our friends. We have been dating for almost two years now and we have been long distance since March, so about four months. Thankfully my job made me enough money to allow me to fly her to me for about a week a month so we did get to see each other fairly regularly. We talked every day, went to bed on skype, woke up to each other, and spend every second talking to each other. I moved to a new state knowing nobody and I have no one else to talk to.

About 10 days ago, a week after she had just visited, something switched in her. She just out of no where started partying really hard, ignoring me, lying to me about what she was doing, and refused to speak on the phone or skype with me anymore. This caused me to go through a week of sleepless nights until I told her that I was done a few days ago. We have had fights about her going out and getting drunk several times. She doesn't focus on her job or school work and is very behind in school so I'm constantly trying to get her to not go out and study.. almost like a parent. This led to a lot of fights. She seemed very upset when I broke up and I told her we can get back together but she needed to prove to me that she cared about me and wanted it by sacrificing going out as much. 

She hasn't done that. She has done the opposite. Has started partying more, ignoring me more, and posting snapchats in pool parties with guys at 5 in the morning. I don't know what to do. She is my every day. I have nobody here to talk to. All my close friends in my college town have graduated and moved on. I have no idea what happened that made her go from being in love with me to essentially not caring about me overnight. I am hurt, distraught, and I don't know what to do. I have no one to talk to.

Can you summarize the given text in a few sentences?
<bot>: LD gf started ignoring me and partying super hard out of nowhere and caused what I thought was a really good relationship to be miserable and I don't know what to do.
