Is my ex gf an avoidant? She's talking to me but won't have a real conversation.

My ex girlfriend broke up with me three months ago. Because she has Chrons and she's worried that I won't be able to step up in my own life and get a car and make things easier for her and provide a home. And she thought that her driving for me made her pain worse and have to have surgeries for it. So we broke up but ended on good terms and she said if I could get my life together we could try again. And earlier in July she reached out and talked about us, sent a picture of us and said how grateful she was for our love, and our memories. And later she sent a video of her saying an inside joke between us and then her crying saying she wished I was there to hold her. She started being affectionate with me and then she went silent and so I reached out to her and she shared a bunch of videos with me but we never talked about us or anything.

Cut to a few weeks later I just reached out to her again and told her I loved talking to her the other week and I'd love to talk to her sometime and hear how she's doing. And she just responded by saying a joke to me and laughing with me and being very jokey. Is she an avoidant and what do I do? This is painful because all I want for us to have is a conversation about us or at least for her to ask me how I'm doing or talk about something serious but it feels like she's avoiding.
