<human>: Give me the gist of the text in a nutshell

So for the past week and a half almost I've been talking to this girl I met online, things are going great and we talk daily and we shared great conversations, have a lot of similar interests and views, and its going pretty fast it seems, which neither of us have a problem with. We kind of talked like we've known each other for years and just clicked really well with each other, and had not issues with being very open about questions asked.She seemed really awesome and caring, and are both comfortable with meeting within a week. 

We have our first date yesterday, on Friday... I picked her up, we go back to my place, cuddle for a bit, watch a few movies, and I realized she was really what she seemed like. One thing led to another, then after things happened I took her back to her dorm. (I asked her about dating cause we both seem very interested in it, and she wanted to give it another date or 2 before making it official)

After I dropped her off, she told me to stay calm and not overthink things (she picked up real fast that I do), so I agree, and to text her when I get home, so I do, we talk a bit and we go to sleep after.

Now it is Saturday, I was aware that she was going to be busy with her family, and then drinking later in the night, and warned me that I shouldn't text her cause her responses wouldn't be appropriate and wanted to keep a good image in front of me (I didn't really care if she did or not), so I just shot her a good morning text around 9 in the morning, and then I went on with my day. It got around to 6 in the evening and I haven't heard anything, so I decide to text her, I get a response, we talk for a bit, and now nothing.

So my question is, am I overthinking things and should I be worried or should I just remain calm and let things play out and hope that Friday night wasn't just a one-night stand kind of thing? If I am overthinking things, what is a good way to distract myself from doing so that I don't worry and bother anyone with it?
<bot>: Talking to a girl for a little over a week, we go on a date then I hear nothing the next day. Am I overthinking or not?
