I (39M) got a match (33F) on Hinge last month. She was very lively and curious about me in chat, but I tried to keep my cool because I have a tendency of getting too attached too quickly. We met a week later. The vibe was great, and I really liked her, but she did mention something along the lines of "I thought you weren't interested in me from the messages you sent." I didn't ask her what she meant by that. I figured she must have wanted me to move more quickly or show her more affection, so I tried to convince myself that she is the one. I got right into setting up the second date and flirting with her after getting home, but she brushed off the flirt with "haha" and joked that "I didn't seem to want to waste words with her and only wanted to get things done." I got confused, but I didn't think too deeply.
I continued doing what I was doing for another 3 weeks. We did have a second date in the following week, which also turned out great, but completely platonic. Then she got sick and busy so we didn't meet for 2 weeks. During the 4th week, she showed a distinct shift in tone, to the point where any time I said anything that's remotely suggestive, she would ignore it. That's when I really started to reflect on the signals she's been giving me. I think what she meant was that my texting style was too fast and straight to the point. I often jump between topics and skip responding to her comments that she was seeking reactions to, and in doing so I didn't take care of her feelings at the moment.
Maybe she was never interested in me, or maybe she was just looking for a penpal, whatever it was, my misunderstanding of her needs certainly didn't help. I just thought it was kinda funny that I took her words the completely opposite way. Of course this is all just my conjecture as I haven't asked her directly. As of right now, I invited her out for a meal over the weekend, but she told me she might be sick again and she doesn't want to pass it on to me. It's probably her way of turning it down. She's still asking me questions, but I don't know if I should continue texting with her, or just be blunt and ask her if we should end it.
Update: I asked her if there's anything she'd like me to change even if it might be too late. She told me I'm overthinking and she really is sick. She did say she wants to slow down. She feels pressure from going on date every week, but she felt sorry for not being considerate of my feelings.
