how to respond to a text from an old friend saying “i miss you girl”

(sorry for the stupid question) In terms of how I feel, I also miss the memories we had together, but I don’t have much intention to hang out with her. The last time we met was in middle school and I changed so much from then. I don’t know what to say cus my usual is response is “aww me too. let’s hang out!” I’m just afraid that if we do (if she wants to), our interactions wouldn’t be the same and it might be awkward. Also I’m not sure if she’s just saying that just cus or she’s suggesting a hang out.
