tldr I feel like I’ve been doing all the chasing and am wondering if there’s a way to save it before she eventually loses interest

I’ve gone on three dates with this girl I met on tinder. My life is kind of a mess right now so I felt quickly like I was head over heels with her. We’ve been texting every single day since this is the dynamic she set after the first date. The problem is that before our third date, she started saying last minute that she was having a rough day figuring out logistics and found it hard to meet up (she didn’t explicitly say no). So I offered to uber an hour to where she was, help her drive her car somewhere closer to her place, and then we went to a mall, got lunch and hung around for a bit. I kissed her at the end and she did reciprocate. But every time I flirt verbally she never reciprocates. After the third date, the texting dynamic has become more like I’m her diary and she tells me what bothers her throughout the day or other random stuff, but hasn’t really been asking much about my day or even if she does, when I respond she doesn’t engage with it. Then she’ll go out with her friends and doesn’t get back to me until later the next day. How can I stop chasing without her thinking I’m trying to be manipulative? She takes hours upon hours to reply. Should I purposefully stop showing her that I’m quickly available to text her? I usually text when I’m available, and it takes me 30 seconds, so I usually reply in under an hour
