Ex came back after her rebound. Can't really tell if she's stringing me along now?

Ok so buckle up for a bit of a long post. My ex and I (both 21) of 4 years and I were living together for several years and we had just moved down to where she grew up in the caribbean last fall. She was anxious to leave, I was broke. Her anxiety spiraled out of control and she was no longer willing to work on us anymore. It was very difficult leaving but I left to go live with my parents and get my shit together. She said we broke up so we could "become stronger individually" and not even a week after I left I found out she was with a mutual friend of ours that is twice her age. I went no contact and we didn't talk for 2 and a half months. She then reached out to me this past weekend.

it's been a several days now since we had talked on the phone and I feel pretty confused now and I'm hoping for advice. 

So she facetimed me on saturday night. When I picked up we couldn't help but both just smile huge at each other and we laughed and caught up for about 30 minutes. She said that I seemed different in a really good way. She seemed different too. Then she started getting into why she called. She started crying. She apologized for everything. For taking me for granted, replacing me with a mutual friend, breaking my heart, forcing me to leave, etc. It seemed very sincere. She went on self-examining herself and her mistakes for the next 2 hours or so. She said she wrote me a letter every single day but was too scared to send any of them. She has started therapy and since then she had realized how special our relationship was and how special I was. That not every guy is kind, loyal, compassionate, etc. And that she had treated me like shit and she never wanted to be that kind of person ever. The way she was owning up to her own faults, not just towards me, but her own personal faults too, seemed very mature and sincere to me. She mentioned how the rebound was abusive and she's so embarrassed about him. She admitted she was only with him because she couldn't bear to think about me. 

I was listening the whole time, trying not to say much. I was worried that this apology was simply out of guilt rather than hope for actual reconciliation. I did specifically ask her "is this only happening because you want to alleviate your own guilt, or because you're lonely bc your rebound didn't work out, or because other people are telling you that you should apologize?" She said that she spent a lot of time with her therapist making sure it was coming from a real place, because she didn't want to string me along anymore. She eventually got to her point - she wants me back in her life, she still loves me, and I'm too valuable to her to let go. She used the words "I miss my friend" and "I hope we can be friends". She asked me how I felt about that, about what I wanted. I told her that I wanted the same thing I always did with her. That I want her romantically and that over the past few months I had learned not to settle for anything less than what I want. And that I am not capable of settling for being friends. She stayed silent. I followed up with "But I don't know how we would even get to a place where we could be in a relationship right now even if we were both 100% on board." I say that because I just restarted my life in Virginia when I left her. And she's still down in the islands and in a high state of flux, she might move to Vegas, Nashville, or Cambridge by the end of the summer and it's just like, how would that even work? I'm not about to pick my life up again for her (as much as I actually want to internally) and she doesn't know where the hell she'll be in even just a few months. She responded "yeah, that's why I was just hoping for communication to be open, because things are weird right now." We sort of agreed to "proceed with caution" with each other. It sounds like she wants us as an item again, but maybe the circumstances still aren't correct.

All in all, that call was about 4 hours long. Over the next few days she sent me a ton of photos of our cat which was nice. Yesterday she was texting me pretty much the whole day. And in the moment it felt good. She got to talking about her plans for leaving the islands. Gig opportunities in Nashville, LV, grad school in Cambridge etc. She mentioned a bit how she really wanted to leave the islands asap bc her work is gone, and she just got out of "relationships that were making decisions" for her. This made me uncomfortable. I didn't like the casual characterization of our relationship as "making decisions for her". and of course I don't like the word relationship being used to describe the other guy either. She kept talking about how she needed a change and stuff. This was upsetting to me. I was sort of hoping that she would make an effort to involve me in her plans somehow. I am kind of planted where I am though. I just got a real estate license and I'm in pretty deep debt. So I am trying to dig myself out of that hole. 

She made a little comment towards the end of that conversation saying " I meant to tell you all that over the phone". Which makes me think that she thinks it's important for me to know where she's thinking of going soon. I wonder if it's her subtle way of telling me that she doesn't see room for "us" in the near future? I just sort of said "ok" and she said good night. I don't like this position of feeling like her friend. But I also want to take things slow and feel out her intentions more? It's only been a few days that we've been talking and I don't want to blow things up and give her the "I can't be friends with you" speech. She had said on the phone she wanted to visit me. And she had been pretty flirty over text the past few days too. 

I don't want to be strung along by her but I also want to leave myself with a path to reconciling fully with her. How do I proceed? I had not been texting her first at all and I'm continuing that. Perhaps I should just not engage in conversations further than a few short messages so she gets the picture. 

Thanks
