<human>: Can you condense the text into three sentences or less?

Everything has been fine all this years, but exactly 6 months ago she went abroad to get a Master's Degree (its a 1 year degree, so she will come back in 6 months). About a month ago she told me she didn't know what was happening to her feelings, she didn't feel the same towards me. And asked me for a "time" but told me that we are still bf/gf... 

This is very confusing to me, we talk everyday still (but im never the first one to say Hi in the day, i wait until she does it), she also doesn't show love towards me, she basically treats me like if i was a good friend of her and that's it. I dont know how to deal with this, i want her to miss me but i dont wanna stop talking to me. I'm worried if i keep a lot more of distance she will fall for another guy. Yet she's the one who asked me for distance but still talks to me everyday. I must clarify that even if we talk everyday it's VERY VERY little, a couple lines per day and that's it. We used to talk a lot more and skyped a lot. Im still being lovely towards her, i tell her i miss her and that i love her, most of the times she ignores it and sometimes she sends me a "heart"  emoticon or says she misses me too or that she loves me too. 

Also, when she asked me for the distance i confronted her (we were in skype btw) and asked her what was the reason of this changes and she said she honestly had no idea what was wrong with her feelings. 

How should i deal with it? 

1) Should i keep more distance? 
2) Should i stop being lovely towards her or should i keep being lovely with her?
<bot>: Gf, who is studying abroad, asked me for distance, it's been a month already and she comes back in 6 months. We still talk everyday. How should i deal with this?
