Whats up with this girl?

Im 13 years old just to tell u. Theres this girl that might like me. I am not asking if she likes me don't answer that. That is not what i am asking. We are good friends and we have been talking to me all week Monday through Friday. We got in this huge fight. We did not talk for about 8 hours. Then she sent me a blank message. We were texting by the way. Really a blank message. She was mad and said that she would never talk to me again. And she sent a blank message. I talked back and she said that it was on accident. I mean really how do u sent a blank message on accident. She also sent me a FWD. So did she really do it on accident, or was she trying to get my atenshin.
