<human>: Condense the text into a few key points

Sorry if this is rambling, I'm on my phone at work...
So I met this awesome girl about 2 months ago and we hit it off great. Whenever we hangout we have fun and make each other laugh . It's been 2 months and we haven't really talked about where either of us want it to go. I have to admit I didn't bring it up because I wasn't sure I wanted to make a commitment and was happy to keep it light and the sex was a nice plus too.

Up until about a week ago she seemed really into me. She would almost always text me first and usually first thing in the morning and would just do little things to show she liked me. But now she seems kind of distant and I feel like it's because I didn't display the same level of enthusiasm as she did, even though I REALLY like her and have developed feelings for her.

Now she's talking about moving 2 hours away for grad school. She got a call from her ex a week ago, threatening to kill himself because he missed her and she told me about it right away because she felt like I should know and she wanted to be honest with me. She assured me she has nothing left for him, but she seemed really drained emotionally from having to deal with him.

I really like this girl and want to keep seeing her, but if she's moving in 8 months I don't want to get too attached just to have to say goodbye. She doesn't seem as interested in me as before, but I think my being a walled off asshole and having to deal with her ex made her distant. 
I know there doesn't seem to be a problem; I'm getting sex with little to no commitment, but I know if we keep seeing each other I'm going to get attached emotionally and since she's probably moving next fall I'm not sure it's worth getting involved.

I'm going to bring this up to her next time I talk to her, so if anyone has any advice or wants to share similar experiences that would be appreciated!
<bot>: Met a awesome girl. Been having fun, developing feelings and unsure how to approach the future of this "relationship" due to new circumstances.
