What is my ex doing

my girlfriend broke up with me about 7 weeks ago due to her getting kicked out of school and having to focus on her life. she didn’t want to bring me down with her. she had good things to say about me in the text. She has lots of mental issues and struggles with depresssion. two weeks later I reached back out on Christmas to check on her. She responded to my first text. Ignored the next. I texted her again the following day to see if she was okay and she didn’t respond to that. Throughout all this time we have been maintaining a streak. Yesterday she decided to double snap me a picture of her with a kiss face twice in a row directed at me. I just don’t understand her intentions and why she still keeps a streak with me but ignored my text message. I miss her a lot. She was my first girlfriend.
