<human>: Give me the gist of the text in a nutshell

I have been seeing this girl for a little while now. We were friends for years, and friends with benefits when we were both single, but this most recent time we started getting together things were different. We talked everyday, hung out on our days off, threw around 'I miss you' and 'can't wait to see you' and other mushy things. 

Things were going pretty good, but one day she started getting distant. There was gradually less talking, she didn't want to make time for me anymore, and when we did talk it was cold and snarky. Now it's not very often, I'm always the one to initiate it, and I really don't like being treated so shittily. 

Things are done, that's not really the question I'm asking. I just wanted to know, if you were in my shoes would you confront her or just walk away and see if she tries to rekindle a friendship of some kind?
<bot>: The title says it all, should I talk to her about it or is it better to just take the hint and go?
