What do I say after I was being, not knowing she had lost her uncle?

I do not know what to say to her. I feel bad; I did not know her uncle had ped away yesterday. I had sent her a long message basically telling her to erase me, because I was fed up with her reappearing and disappearing in my life. I brought up the instance of when she called me on Thursday for like a minute and said she’d call me back, but never did, even to this day. So in my mind I was like, screw it, I don’t need my heart getting hurt by her again. Yeah we have a past of being on and off, with her leaving me, I thought this was another one of those instances; in which she probably got with someone else. So I end it with telling her to delete my number, erase me, and to get rid of the hoody I had given her from the last time we were together. I did it out of anger because I felt like I was being doped and played out by her, because she wouldn’t text or call me, even when I would try to communicate with her. So then she messages me back saying: Look right now I don't need this from you. My uncle died yesterday and I'm a wreck so don't message me with **** you don't know and what you want. I don’t know what to say to consul her.
