Sharing Feelings

I met this girl in grad school in the Fall and we get along really well. We text almost every day and have hung out several times just us and we both have good times. At the end of the fall, she told me she couldnt get into anything right now and shed worry that if things went bad we wouldnt have a good friendship. She brought up her past and I told her I get it and Id rather be friends than nothing. While the end of that semester was a little rough, the spring was great. We texted more and and hung out more. I tried to get the feelings I have for her to go away by distancing myself, but she interpreted that as me hating her. After that we were fine. But again, I still have feelings for her and Im not sure if Im even in a position to share how I feel because the friendship is established and boundaries were set. I just dont know what to do and i get frustrated when she sends mixed signals/flirty stuff because of what she said. I feel boxed in
