What would you have done

I’m in a terrible dilemma. I live on my own and have kept myself as safe as I can. I bubble with another single friend. I don’t see my daughter and her three children or my son and his two children. My daughter called me the early hours this morning. Raising her voice saying can we come to your house. ( meaning her and her three children). She was really upset. She broke up with the children’s father a few years ago. He isn’t a nice man and has in the past laid his hands on her. But to my dismay she’s let him back into her house. She didn’t say why she wanted to come round but I would assume because he’s been up to his old tricks again. I really panicked when she shouted down the phone can we come over. As much as l love my daughter I kept thinking about the virus. I said I can’t let you come over. She slammed the phone down. Ten minutes later she called again she was begging me so in the end I reluctantly shouted back ok I shouted because I was really scared for myself. I felt so scared thinking this is it I’m going to die now. As I don’t know if they have the virus nobody does. Anyway ten minutes later she called again and was really angry and upset and said don’t worry I’m not coming I know you don’t want us there. I felt relief at first but now I feel so guilty and worried about my daughter. I’ve laid awake best part of the night worrying if she’s ok or not. She must think me a terrible mum. In hindsight I should have put her first before the virus. I don’t know whether I did right or wrong. If I tried to call her she probably wouldn’t answer it. She must hate me
