<human>: Could you distill the essence of the text into 1-3 sentences?

I've been with my girlfriend for over a year now. We have a LDR only during the school year. We try our best to visit often (once or twice a month during the school year). 

Whenever going about my day, I would update my girlfriend on what I'm doing and snapchat her often. On her end, there isn't much communication. For example, she doesnt take the initiative to see what I'm doing during the day. I'm putting in the effort on my end to communicate with her, but she isn't reciprocating. In her defense, she does more extra curricular activities this semester. 

She usually stays up late (up to 3AM) but now she is usually tired by midnight. In the past, we would talk about our days through phone and facetime. Now, she is either not wanting to talk or when we do, she is busy doing other things and I would have to initiate all the conversations. 

Recently, I called her and she said she was going to shower and said she would call me back. I waited over an hour for her, but she never called and the next morning, she said she knocked out.

I've tried talking to her about communicating with each other more, but she always says that she's busy. In the past, she would always find time: after class, in between activities to call me but this semester has been different. Moreover, when she has a big event happening such as a party or meeting, she doesn't want to elaborate on the details and says basic things such as the event was okay, good.

How can I improve the communication in my LDR relationship?
