<human>: Can you summarize the given text in a few sentences?

I'm currently conflicted with myself about whether I should contact a really "good" friend of mine or not. 

So the situation is that I moved out of the country for a four months because of uni, and this girl who is a really good friend of mine sort of seems to be steadily cutting contact with me. And I feel like I care much more about her than she cares about me and that gives me an odd feeling inside. 

We used to be pretty close talking everyday and hang out quite often, and since I left we still really talked quite a lot. Few weeks in we reduced chatting to once a week, because we were both pretty busy with uni. Now I've only got a few weeks left before I return home, and it seems like she is cutting contact with me. 

Since I left we used Facebook, Imessage, and Snapchat to keep in touch with each other. The last time we talked was a month ago, in which the conversation was initiated by me. She used to tag me a lot on stupid Facebook posts and she quit doing that too. We had a snapstreak going on for over 100 days, which she also "broke" a few days ago. I know it sounds stupid, but it's about the principle. 

So now I don't know if I should text her like "Hey Julie, why don't we talk anymore?" or just drop her too as if she doesn't seem to care either.

I know it sounds reallt stupid, but it's bothering me for days whether I should contact her or not, and what I should say. I mean if she's not interested in being friends anymore, I don't feel like putting anymore effort in it. 

I would really appreciate some advice :) 
Oh, and I'm not a native speaker so I'm sorry for that
