I appreciate your response. I have taken stock of this and have apologized...more than once. I've been nothing but honest and open with her. I expressed how I couldn't help the lack of time (dissertation proposal), but it was temporary and I was looking forward to making it up in the winter with her. I may not have had much time the last few months, but I've still tried to be a good boyfriend and I've never been anything but warm and loving with her. I've tried to be there for her as much as possible and have given her more time than anybody else, even myself. I'm not perfect, but I really don't think this should have led to a vanishing. These are issues that most couples face at some point and can usually be talked through. The semester is over and now I have tons more time...she knows that. The blame, the sudden personality and behavioral shift, the unwillingness to talk or even hear me...to see me, isolating from her friends, not posting on social media as she normally does, not even really breaking up with me officially? Some of her friends even think her recent behavior odd. These are some clear signs of depression. She also had a busy month in Dec...a big job application that took forever, medical bills that stressed her out, her dogs were fighting each other. As I said, I'm not perfect, but there is much more at play here. I want to work through this and think if we just talked about it openly and honestly that we could get through it and even strengthen our relationship. I'm willing to put in extra effort. But, it's up to her to meet me halfway, I suppose.
