Errr...whatd I do wrong?...why did she stop talking YET AGAIN?

SO this girl and I was talking, just started talking like 3 days ago AGAIN..after a 5month span or her not talking, she recently sent me a messege asking how I am. I said im fine thanks. She told me blah blah going to college blah blah. Anyway I was like cool, hope you get through life and be happy, have a good time bye. Anyway, I wrote a messege to her asking what hobbies she has and now SHE IS IGNORING ME YET AGAIN>>>I swear I am going to give up on her..freakin stupid. WHAT AM I DOING WRONG?
