I think I'm becoming someone's limerent object and I'm not sure what to do

I (F30) met a woman (50F) 1.5 years ago at a friend's birthday party. The next day, she found me on FB and sent me a message asking me out. I was very flattered and was really seduced by her straightforwadness and drive, and said yes.

I was not looking for a relationship at all, I was enjoying being single (and I still am), having fun, going on dates, having casual sex, which I told her on the first date to set realistic expectations and to not lead her on. She was ok with that and we started seeing each other casually.

The first 3-4 months were amazing. It was a lot of fun, the sex and chemestry was mind blowing, she used to be an athlete and is still in an incredible shape so we went and did all sort of sport activities, climbing, hiking etc etc. I have amazing memories from this period. Since we were getting along very well and also developping some sort of friendship outside of casual sex, I made sure to check in regularly, to ensure we were still both comfortable with the fling we had going on, to remain transparent with each other, and ensure that if one of us developped feelings we would take the best decision to avoid anyone getting hurt. Each time we had a check in, she was saying that everything was ok and that she was happy with how things were and that it was all fun and casual. But little by little, I noticed behaviors that became more and more intense: I won't go into too much details, but for example, she started getting anxious when I was not responding to texts fast enough, she was craving constant communication, sending good morning / good night text every single day even if I was not reciprocating and clearly communicated that I did not have the capacity to text everyday, at my birthday she sent me EXTRAVAGANT gifts despite me clearly telling her I was not comfortable with gifts, she introduced me to her daughter unexpectedly (she has 2 adult children) when I clearly told her I did not feel comfortable being introduced to her family since we were just seeing each other casually..

I managed to gently tell her I was getting overwhelmed, and she admitted having developped strong feelings for me and having a hard time with keeping things casual. We both decided it was better to stop seeing each other and go no contact for a while. We had one last date which was really great and fun, and at the end she hugged me super tight and started to cry a lot - I could see she was in a lot of pain. I felt really guilty, I really just wanted both of us to have a good time and I never intended to hurt her, and I wondered if I led her on and what I could have done better to avoid that.

Then we went no contact for almost a year. She broke no contact in January this year to wish me a happy new year. She sent me a beautiful audio message to tell me I was the highlitght of her year, that she is grateful for all the moments we had together. I was happy to hear from her, to hear that she has doing great and that she kept good and positive memories from our fling of last year despite the heartbreak she had, and I answered to wish her a happy new year too and many good things, without entertaining the conversation further. She replied with another long audio message, kind of repeating the same thing, that she wishes me the best etc etc... Did not answer that last message because even if I was happy to hear from her I wanted to avoid giving her the impression I wanted to go back to talking everyday.

Then, one week after, on a Monday morning, I see another message. I open it and my stomach drops. It's A VIDEO OF THE EXTERIOR OF THE BUILDING WHERE I LIVE, filmed from the window of her car passing by, followed by "Good morning! Have a great day! 😊"

My first reaction was freaking out. I just felt so creeped out to receive a video of my home from the outside, like, idk, doesn't it sound like baby reindeer shit? But then, I rationalized it and remembered that she used to drive by my appartment to go to work every morning because it was on her way to her office. At the time we were seeing each other she would sometimes stop by my place before work to steal a kiss. Maybe it was just her way to tell me she remembers these little moments when she drives by my place.

I did not want to make a big deal out of nothing as I knew she did not have bad intentions so I just answered a brief "Good morning to you too".

To which she answers: "Thanks! The video is just me coming off the bridge saying good morning. So I thought I would just send it to you and wish you a good day… 🙂"

I don't answer anything to that, and I move on, even if I'm still a bit shaken.

In next couple of months after that, I bumped into her "by coincidence" at least 3 times in my neighborhood. Each time she seems absolutely overexcited to see me and we chat a little bit, then I politely say I have to go and I keep walking. Then I receive long audio messages, to which I always answer politely and nicely, but very briefly, with no signs that I want to keep the conversation going, but she still replies with more and more long audios and I usually just stop answering as it's just getting repetitive and intense and not going anywhere. She does not even ask me out, or asks me if I'm interested to see each other again, she is just sharing about her life and how I am amazing and how she thinks of me often and I don't know what to answer that....

Last time I bumped into her, she told me she had started doing jiujistu in a gym nearby, which is why she is often around ib my neighborhood. I used to be an MMA fighter so I do jiujitsu as well, so I chit chat about the topic briefly, like "ah good for you it's a great sport hope, hope you're having fun", then I say I have to go, and keep walking and go on with my day. IMMEDIATLY AFTER I RECEIVE A LONG AUDIO MESSAGE from her telling me she was so happy to bump into me and then she keeps talking about jiujitsu. I answer briefly again along the lines of "great to see you too, not surprised you like this sport, have fun 🙂" AND SHE SENDS ME AN OTHER LONG MESSAGE FOLLOWED BY A BUNCH OF PICTURES OF HERSELF DOING JIU JITSU. I stopped answering after that.

That last exchange was a couple of weeks ago, and yesterday, I'm pretty sure I saw her car pass by, and I kid you not, I IMMEDIATLY STARTED TO HIDE TO ENSURE SHE DOES NOT SEE ME.

I'm having a complex mix of emotions right now because I do keep amazing memories of our fling last year, even if she started being a bit intense by the end, I did genuinely have an amazing time with her and think she is a great and kind person, and I would have been happy to reconnect after a long no-contact and catch up as I really appreciated her, but the way she is going about it makes me so anxious. I don't know if I'm overreacting, I'm sure she is not ill-intentionned but I just have this feeling of my stomach dropping each time I receive a message from her since the day she sent me a video of my building. I really don't want to be creeped out, I know she is not a bad person, but a part of me does feel very creeped out despite my effortd to rationalize things and not make a big deal out of it.

So far, I have not received any other messages, but if she comes back with long messages / audios / videos / pictures, how do I nicely tell her I am a bit overwhelmed by the intensity of the messages? I feel so guilty to feel that way knowing that she means no harm at all.

We also have a friend in common that I am close with (the one friend that invited me to her birthday 1.5 yrs ago where I met this woman) and I don't want to make things weird if we get invited to a get together / birthday or whatever.

Also, I am her first same-sex experience after her coming-out, she came out super late (when we met apparently she had just come out, she spent her whole life in the closet and even had a 15 yrs marriage with a guy) and I have a lot of empathy because it must be so hard to hide your true self for so long, and maybe it has something to do with why she is so intense. I experienced strong limerence when I was much younger (like between 19-22 yrs old), during my first experiences with women, so I don't want to be too harsh as I know how hard it is and how intense it is when you finaly experience same-sex intimacy after years of shame.

Any advice would be appreciated. 😩
