Is she into me?

I first met her last November. She is not only the most wonderful girl I've met, but the most wonderful human being. We lived in the same room for 6-7 months (conscription). For the past 6 months, we have spent a lot of time together, way more than with other people from our unit, mostly playing video games for hours or watching videos and movies. We have gone out together a few times during and after the end of the conscription, with her proposing to go out a couple times as well. She is really cheerful and talkative when we're together, but since we now live quite far apart, cannot meet very often and she seldomly texts or sends snaps to me unless I contact her first. For the past few months I've been so puzzled whether she's into me or not, because I sure have terribly fallen for her. This is killing me.
