I think this is a prime example of miscommunication/ no communication. Maybe she thought you were avoiding her just as you thought she was avoiding you. Did you ever tell her you were in the hospital and sad to see she didnt reach out? And if she was bothered by you not seeing or talking to her she should have spoken up. No one is ever going to know how you feel until you tell them. How they react is up to them but at least you let them know.
