I (33M) am not sure what this woman (33F) is doing?

TL;DR: I recently ended an engagement and it’s been tough. A friend of a friend, Amber, checked in on me and we’ve hung out a few times with mutual friends, often talking for hours. Though I’m not ready to date, I sensed some chemistry. She admitted she had a crush on me while I was engaged and said our mutual friend Maria was upset about it. We texted for days. I suggested hanging out, but she always had a reason why she could not. She later suggested hanging out. When the day came to hang out, she was going to share more details with me and she never did. She pretended like she never suggested hanging out. She later said she will be the “friend” I need. I’m not trying to pursue anything, but I’m confused—was she just being friendly, or is there more going on? It seems more like a platonic thing to me. I did not text her back after the last message. Maybe I should just say Thank you and move on so that any mutual hangouts with friends won’t be awkward?

I ended an engagement and it has been very tough. I am appreciative because my friend’s friend Amber reached out to see how I was doing and if I needed anything. I took it as her being friendly. We hung out a couple of times with mutual friends and ended up talking for hours. It is inappropriate (I fully acknowledge), but I felt something between us. I am not anywhere near close to being ready to date.

She started texting me and this went on for days. She told me she had a crush on me when I was engaged. She also said that our mutual friend Maria got mad at her when she told her that. I asked her a couple of times if she wanted to hang out (literally just to hang out). She suggested we go somewhere instead the next day. She pretended that she never asked me this and completely glazed over it. Then she told me she will be the friend I need her to be.

I am not looking to date, but I am confused by the situation. I am most confident she is just being friendly, but I sense there is possibly more here too. What is likely going on? I did not text her back after the last message. Maybe I should just say Thank you and move on so that any mutual hangouts with friends won’t be awkward?
