הכרויות חינם|תמיכה עבור סקס

I'm 33M. I matched with this woman (32F) few weeks ago. Last Friday we finally met for dinner. The date was honestly really good. We talked almost 4 hours without feeling bored. We laughed a lot, walked after dinner, and conversation was easy the whole time.

Before we went home, she suddenly said, "Sorry if I looked too enthusiastic. I know it scares people away."

I was kind of surprised. I asked why she said that, and she just smiled and said she learned from past dating not to look "too excited" too early.
I told her I actually like that she looked excited. For me that's not a bad thing at all. We hugged and went home.

But after that, her texting changed. She still replies, but much shorter now. Before she used emoji and asked questions. Now it's mostly just short answers.

Maybe I'm overthinking, but it feels like she's trying to hide her excitement now because of what happened before. Should I bring this up with her? Or just pretend I didn't notice and let things happen naturally? I don't want her to feel she has to act different around me.
