<human>: Can you condense the text into a few key points?

The relationship started off as long distance, i just recently moved back to the state i used to live in and where she currently lives in.

In her past she had a 2 year long r/s that was probably not healthy for more than half of it.  She has a difficult time communicating, and i can have a hard time explaining myself.

She is a pharmacy student, almost done, but in her last schooling semester.  I work full time as an engineer.  

At times i'll do things she wont recognize, and many times she does, but there are certain things we just sort of miss on.  No doubt pharmacy school has effecting her thinking. She's admitted it.
When she has exams i really cant see her for about a week and a half too two week time period.  Not a big deal, we text all the time, call each other, even video chat.  

Current issue:
I dont feel like she is thrilled/head over heels when she sees me or gets a cute gmorning text.  As i tried telling her that today before she got to studying, she complained that i was "doing" this to her.
<bot>: I'm just looking for tips on how to approach my gf to tell her she could be a bit more affectionate, when we barely talk because she has to study.
