Is she no longer interested or am I reading too much into the situation?

Went on a great first date with this girl the other week on a Tuesday, we were there for 3 or 4 hours and the conversation flowed easily. Got her number and followed up for a 2nd date a couple days later. She invited me to come hang with her friends on that Saturday. We had a great time, I was getting along really well with her friends and having good conversation with her. I spent the night in the same bed as her and hooked up a bit. I left town for a few days that Sunday and she had plans the following weekend over 4th of July weekend, so we said we'd do something this week. She texted me last Tuesday saying she hoped I was having a good time with my family. Went 6 days without talking to her after that, as I wanted to leave her alone and let her enjoy her trip for 4th of July weekend. Fast forward to today, she's now back in town and I wanted to see if we can set up a 3rd date this week so I sent her a text today saying "Hey hope you had a great time this weekend! Would love to see you this week, are you free on Thursday?" and she didn't respond. What should I do?
