Asking a girl out via text on our 5th date. First 4 were great....Had sex on the 3rd. We had a good time. She’s being aloof with my texts past 2 weeks as if she’s annoyed at me. Now today I’m texting her to setup the date and she’s taking 3-4 hours to respond to my questions where I’m asking if she’s available

This girl has expressed and shown a lot of interest in me and I’m convinced she’s just playing games but my question is how could I confront her in a way that doesn’t make me seem emotional ? Thanks a lot in advance

Edit: we Snapchat and have a 110 day streak so it’s hard to go ghost for a few days. I understand she’s probably fucking someone else but how do I approach this? Hard next?
