Long lost love? Does she feel this same pull that I feel?

TLDR; We have talked on and off for years, and theres always been incredible chemistry, and i know years ago the feeling was very mutual, i cant help but feel it still is, and that shes hoping to rekindle something between us.

I am 28M. This woman is the same age as me.

We met over a decade ago as Jr.s in high school, and she was a foreign exchange student from Brasil. While in high-school we both had crushes on each other, but i was kind of a huge POS at the time and was only interested in hooking up, so I avoided her romantically because I knew we got along so well we'd end up dating.

We had loosely kept in touch with a message back and forth to eachother. When we were around 20-21 we had started talking to eachother a lot more and had discussed trying to do a long distance relationship, but she was all the way in Brasil, and i was in the PNW, and at the time I was a wreck, I wasn't in a space to be with anyone, I needed to be alone, because I still hadn't quite gotten over the POS I was, and in my heart I knew I'd mess everything up if we dated. If my memory is right we did eventually briefly long distance, it was either just before or after she had ended up sleeping with a professor that I'd felt something was off about because of how highly she talked of him, and I had a feeling he was the kind of guy to take advantage of that, and he did. She'd clearly felt awful about it, and while I felt awful, I knew who I was at the time would've done the same thing in her position, and I just couldn't bring myself to be mad at her. Eventually some intense depression came over me and I pushed her away, and she had her own mental stuff going on, and we ended up splitting off pretty brutally.

I'd thought of her pretty often, at first everyday, eventually once a week, eventually once a month, it was always this yearning of how much I wished things could be different, and how I wished I could not only be different, but better for her. If I remember right I'd seen that she had gotten married, and shortly after she had blocked me on all social media out of nowhere. I felt sad about it, but we hadn't talked in at least 2 years at that point so I got over it pretty quickly. Around 24 I'd gotten into a horrifyingly toxic relationship with a woman that was constantly gaslighting me into believing she was separated from her husband, in my heart I knew she was lieing, but I so badly wanted it to be true I let myself continually get played and used. Sometime in the middle of that this woman randomly unblocked me from things and sent me a message asking how I was doing. I was in such a bad place, I believe I just lied in my response about how great I was doing, and she'd at somepoint said she had a dream about me if I remember right, it was a short exchange, but it destroyed me for a few days because I knew what I felt like I had missed in my life.

At 25 I met a woman on tinder, and we saw eachother for a few months, and almost immediately after we made it official she'd gotten pregnant and we had a kid. At somepoint I happened to see that that woman from Brasil had gotten divorced, and in that moment I had the weirdest realization that if she had reached out and wanted to be together I would have left this woman and figured out what to do with our kid. That moment though I knew I didn't love the mother of my child, and eventually earlier this year I couldn't handle how unhappy I was with her anymore, and we broke up. Not long after, I can't remember who added who, but we ended up becoming friends on Facebook and Instagram again. We didn't say anything to eachother though. We just left it like that. Me having this pull towards her still after all these years, I felt like a creep. I saw a few posts of pictures eventually that showed me she was in a relationship, this time I wasn't sad, I felt happy for her. I hoped she was happy, sure I felt a little down somewhere deep in my chest, but I ultimately just knew I wanted her to be happy and felt like she deserved the world if that's what she wanted.

That takes us to now. On Friday out of nowhere she sent me a message, and what started off as a brief exchange turned into us catching up the rest of the day, and it seemed to end there. Then yesterday she posted something publicly about issues she was having emotionally, and I reached out to her just to tell her it might be stupid, but if she ever needed anything she could just ask and I'd figure something out. We ended up talking more and she eventually asked if i was seeing anybody or planned on it, I told her the truth, that my daughter is only living with me for 2 more months, and ive been stressed out the last several months, so I don't have the time or confidence to try and meet someone new and split time with them and my daughter. She told me when asked in return that she had been dating a guy for the last 3 years, and they moved in together in March, but that things have been going poorly since then, and she had this feeling that it was going to fall apart. Our conversation came to an end again. Today we loosely talked on and off, but it feels very much like we're both being coy talking about wanting to visit the cities we live in now, [I left out that while catching up she told me she'd moved to the US 3 years ago] and she kind of left it off a bit ago, before i started writing this, that it would be nice to hangout too. Her intermittent responses today though were different than yesterday, it gave a feeling that she was responding to me when her boyfriend wasn't in the room. Having been in that toxic relationship I remember the same feeling of her responding at intervals that felt like someone had briefly left the room, or that a text was done quickly.

This is probably all me just being stupid, and hopeful. There's just this part of me that feels like she feels the same way, this energy that feels like being pulled to eachother. Having gone through that toxic relationship, and having a kid, I'm not the POS boy I was back then. I feel genuinely like I've become a much better person, and that if we tried we could make it work now. She's in a relationship and I wouldn't ever do anything to push her to end it. I just feel like she wouldn't reach out if she wasn't already unsure of the relationship. I'm actively trying to just keep thing friendly like two old friends catching up. I've already made the decision not to cross that line of discussing feelings unless that relationship ends and it feels like she's also wanting to have a conversation about feelings. I just don't know if I should give up on that hope in the back of my chest or hold onto it. It's a wierd position to be in, and I don't know how to feel about it. Because of my feelings, I think I should just take a step back so as to not put her in an uncomfortable position. Anyways that's what's going on if anyone has any input, Advice, or opinions.
