<human>: Can you succinctly summarize the text in 1-3 sentences?

So there's this girl I've known for about a month, but we've been talking daily for almost 2 weeks. She actually initiated the friendship. Last week, she did invite me to meet up with her at the bar, and I agreed. We had a few drinks, played darts, I took her home, etc. 

For the past few days, the conversations have slowed down a little. Like she often takes longer to text me than she usually does. However, she does respond 99% of the time, and she even initiates. Our main form of communication is Facebook chat. I'm on my computer practically 24/7, and she shows up in my righthand chat column on Facebook. Sometimes it will show that she's been green (available on Facebook or chat) for 10+ minutes, yet she won't even read my message until WAY later. 

Example: Right now, she asked me a question, which was if I ever played Rainbow Six. I told her yes, and that it's pretty dope. She's been in and out of "Green" (available) for over an hour since I last sent it. However, she hasn't even read the message. 

I really like this girl, and I want us to get closer. However, my car has been fucked up. It's getting fixed tomorrow, though. I really like her, and I want to get her interest back? What should I do? Am I just over think it?
<bot>: Started talking to this one girl. I really like her, I am scared she's losing interest as she's replying a lot slower. What should I do?
