I hate all this overthinking. Should I confess or not?

There is one girl I can't get out of my head. I've known her for 6+ years. She is my crush. We were in a car together about a week ago, and she leant against me even though it could have been avoided. And she let me touch her breast with my elbow for the whole ride ( she had done this before, 4 years ago; this was the second time). After that, one day in the morning, while I was sleeping, she ran her finger through my hair. And after that, one day during the evening, while we were sitting , she flicked her finger on my knee, asking me a question, "Does it hurt?" with an angry expression on her face. To which I replied, "No." I noticed that she looked and smiled at me during are stay. I don't know if I should take it as a sign. Some of the signs she has shown are like she laughed at my unfunny joke, offered me one slice of orange when I was in another room (she actually came walking to the room which is 6m away) and touched my nose. It 's been 4 days since I thought about her. Should I confess to her that I like her? English is not my first language. Sorry if you find it hard to understand. Thank you.
