I'm sorry to hear this. I've experienced friends being distant with me a lot. I would say, after college, people graduate and then they become separated geographically. After a while it can be natural to lose interest from those in the past. Things change and so do people.
I'm not so sure if telling her, "she's being a bad friend for not texting you" was a good idea. That may have come as being too blunt. Although I completely understand how you feel and I agree with you. But there's no real easy and nice way to handle it.
Overall, I think you should move on from her because it sounds like she's lost interest in you. I could be wrong, though. Like I said, these things happen, and it's happened to me a lot. As far as you saying that this year has been bad, there must be a lot of that going around. Because it's been a bad year for me also and for some many others I've spoken to.
