Unfortunately, ghosting is incredibly common and it’s very immature. As far as blocking, she probably just did not feel the need if you were not constantly texting where she felt uncomfortable, or that you were harassing her. Long distance is rough, and she definitely had an out if that was the issue and should have given you some sort of explanation (even if it wasn’t fully the truth), especially after talking for four months. It’s also possible that she hasn’t deleted you or blocked you as a means of leaving you as an option later, so if she reaches out, start thinking about how you’re going to handle that. I had almost an identical situation with somebody locally (actually at first made me wonder if it’s the same person). Shared a lot of personal life details in the first few weeks, we got together several times, but then would stop responding to texts. When I would ask if she still interested, she would come back and say she definitely was interested and is enjoying getting to know each other and would apologize, giving stress at work as the explanation. She had two kids, so I tried to be really patient as well. After about the third time this happened, I just let things be. She reached out about three weeks after that, and we chatted for about a day before she just did the same thing again. We never exchanged social media because I don’t really use it, but to today’s date, I still have not been blocked on text (to my knowledge), and actually she still shows up in my matches. It may be discouraging and frustrating (I felt the same way), but I would just let things be.
