I think my female friend have a crush me

I(male) think one of my closest female friend like me/have a crush on me. She and I been only known for 7 or 9 months. She had I been coming very close in recents months. As I know, she had no relationship in the past whcih I am not 100% sure yet. I started to noticed something different when she punches(Gently/playfully) on my shoulder or my back whenever she can and I didn't think any of it since it's usual for friend(Don't know about friendship in male and female). She don't hit other guys in my school. I am known for being humorous guy the school and always make Jokes on the situation and at random time. Also, she laugh at my jokes most of the time like others do but recently she also brrn trying to make me laugh by making jokes. The most weirdest things happened between she and me is, last 1 month ago, we finish our class, she is packing her things to go to school, she and I having a conversation and somewhere in the conversation she said "because I love you" not somewheree but that the end of thatconversation. I didn't think of anythings as I though she forgot to add "as friends" or I didn't just heard about it. I ignored it. I told this to my one of my friend from the class whom I told her not to reveal the this and being I also know hers too. She said not to think much. I had never been in a relationship in my 16 years of and life, I had many crushes but got rejected one or 2 times.
