What does this mean? I’m confused

So I like this guy and we have talked on and off for about a year now and his sister is my bff and she always tells me how he calls me his baby girl and how I’m beautiful so we have been sc and texting and on Friday I went to his soccer game with some of his family and afterwards I went over to his house to eat and when I was about to leave he walked me to my car and we talked a little bit then he gave me a hug and told me to text him when I got home so I did and before I went to sleep we sc and texted for a little bit but what I’m confused about is that now 2 days later he hasn’t really been talking to me what does this mean?? Why isn’t he talking to me??
