Should I break things off or should I keep trying?

Recently I (31M) took this woman (30F) on a first date/ feeler this last Sunday. We spent about 8 hours together where we walked around a park and grabbed food. After we went over to her place and made out and watched tv together. After the date, we had made soft plans to see each other Friday.

During the week we texted semi frequently about our day and surface level things. A couple days before we were supposed to meet I asked if we were still good to see each other on Friday. She got back to me later during the day saying she had to work an evening shift that day and asked for a rain check. I asked her which day would work and she told me next Friday. I told that works and shifted the plans around to make the date more casual.

Ever since I confirmed the original date with her, I’ve had a feeling that she’s lost interest since her texts have become even more spaced out and she suggested a week from our original date. Am I overthinking this interaction? Is this common for women?
