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

As the title says, this girl and I used to date. We dated off and on for four years, when we were both teenagers with a lot of issues. We have known eachother for roughly eleven years, and talked sporadically since we finished dating. Well. I recently had to go to training for my job in the city she lives in, and we met and caught up. At the time, she was engaged. Fast forward about a month or so since we started talking again. She broke off her engagement. The day after she did, she asked me to drive down to see her (roughly and 8 hour round trip) , so I did. I got there and picked her up from her apartment, and on the way out of her complex she called her ex-fiance and told him she was out of the apartment, so he could come get his stuff. So, she said she wanted to go see a movie. We get there, I buy our tickets, and pretty much as soon as the movie starts she asks me to take her home. I didn't do anything, no touching, or kissing, or anything. We haven't talked since, and only exchanged a few text messages. This girl was my first love, and since we started talking again, I've been feeling myself getting more and more attached. She's mentioned the same thing to me. So, should I be concerned with this radio-silence? Should I reach out to her, or give her space? I've never been in this situation, and I can only imagine how difficult it must be for her. Ultimately, I just want her to be happy. Preferably with me, but if not, that's cool too, so long as she's content. 

Thank you in advance for any advice/help.
