Never make someone who loves you, cry. She may have not cried that much for anything except the time when you thought of leaving her. That little time you had with her may be something she might be living her thoughts by her life. Those sweet and hurtful moments would only make her tear. That's true love. She misses you. She would take good care of you when you are just hers. You could have taken things lightly but for her it may be her dream. Knowing that you will be leaving her, shattering her dreams, she would never want to talk to you. But sadly, the love she had for you has never entirely gone. Therefore, she would make many attempts for you to speak to her so that she doesn't feel she is much disconnected from you. It would just make her day if she sees your 'hi' message. You may have many priorities but for her you may be her only priority. She doesn't know much on controlling her love emotions for you. All she knows is to unconditionally love you.
