How do I get out of my own head about my ex?

My ex and I broke up nearly 4 weeks ago and I am seeing her again next week. I saw her 2 weeks ago to talk and we cried it out and we both apologized and I told her how I can do better and she forgave me but said she doesn’t know if we can be more than friends right now because of some unhealthy things we went through. She know feels she needs to be on her own to learn how to put herself first and tackle things on her own and be her own person and that if we try again right now the temptation to rely on me as a crutch is too great. Im still deeply hurt because we haven’t given it 100% so I don’t know how she can just feel it in her heart right now. She told me she sees the possibility and that for now we can text as friends. Well fast forward 2 days later she calls me crying saying she misses me and she loves me and it’s just been too hard to pretend over the phone and the texting is just too fake and it’s bothering her. I said let’s go indefinite no contact but she said no and to text her when I am home for spring break and we can hang out. That made me feel slightly better knowing she’s still grieving the relationship but the past 2 weeks she seems happy going out on social media and stuff and I know there is not another guy so im not worried about that. My fear is that she will be too hard headed and closed minded as to what I have to say when I talk to her again and is forcing herself to forget and not remember the good. And that she’s forcing herself to only remember the bad that way it’s easier to say the good she shared with her friends is miles better than our relationship and that she’s better off without me. I just want her to realize that we can have both given that we are working on the things we agreed that we would work on. We never communicated properly about these issues and she pulled the rug out from underneath me with the breakup because just hours prior she still talked about marriage and such. Can someone help me get out of my own head about this because I don’t want her to just close me off and be cold towards me even tho there is no indication of that.
