Do I have anything to worry about?

Iv been texting and seeing this girl every week since the summers started and she usually texts me every other day every week. Iv known her for three years and she thinks I'm hot and I really like her alot. When she texts me she sometimes asks me to come over and hang out for a bit. However, a week ago I went to her house in the morning and I thought she looked really y in her outfit and after I hugged her, I tried to lean in a kiss her but she pulled away. I said sorry and she "it's all good" then she looked at me and smiled. I believe her that everything is cool but I still felt bad. Anyway she hasnt texted me for the whole week so I texted her during the week and she seemed ok but at the same time she seemed like something was bothering her. I thought it could have been me trying to kiss her but I remember a couple of days before the incident she was Mad at her parents and she was reacting the same way. I'm getting worried because she hasn't texted me since the incident and she seemed ok with it but I don't know what do do. She seemed to like it when I kissed her on the cheek but she wouldn't let me kiss her on the lips.
