A MOTHERS CRY!!!!HELP NEED ADVICE‼️‼️😔😭

I have a 18 yo dtr who is in a relationship with a 22 yo accused of raping and strangling a person. I have cried out to my child that I don’t want this for her. When she lived with me she begin to rebel I set her up to be able to do great things and she rebelled. She wanted to leave but I blame myself for not making her stay with me but it wasn’t good she started to get so disrespectful and the more I tried to get her on track she rebelled. She dropped out of school so she has no diploma when she was so close to graduating. And now she has link up with this situation and all I find myself doing is praying and crying out.. she won’t listen to me. Part of me want to go get her but that might make her rebel more against me and if I do that put all my effort into getting her and she proceeds to not listen as she told me she is in a perfect relationship with this man and she doesn’t care how I feel about it😭and hung up on me! I could do more damage than help. I just want my baby to wake uppppppp!!! I just don’t know what to do!😭😭😔
