End it or not? what to do?

Last week a friend and I had gone out. She told my parents that we would be going to a church event while I told her mother that we would go a bonfire and that we will both return by 11 and that I would take care of her it was homecoming week and we had drank a bit the person who was driving us couldn't take us all the way home. My friend and I were about to walk home but I came back to the driver convincing her to take me home in exchange for money. I tried to find my friend so we could both go home together but I couldn't find her. I got home around 12 but my friend was walking home with another group of people. Around 2 in the morning her mom came to my house asking where she was I told her I lost her and that if I could contact her daughter I would let her know. My friend didn't go home until 3 and when we attended school that day she told me her mom did not like nor trust me anymore I thought we would still be friends but she started avoiding/ignoring me and when I talked to the group she walked with after I left her they said she was really upset of me leaving her. I thought of going to her house and apologizing to her and her mother but she already told me that once her mother dislikes someone she dislikes them nothing will change that. I thought she was only giving me advice as to not make her mom anymore mad but I had another talk with one of the people in the group she walked with that night he said she was really mad and basically said stuff that she doesn't see me as a friend anymore. I made up my mind to end my friendship with her since her mom did not trust me anymore and that at the end of our school year I will be leaving to another country not wanting to be hurt being too attached. Now for the past days I have been avoiding her. Yesterday she asked why I was mad but I just ignored her walking off. Today in the morning her along with my other friend asked why I was mad a her but I just put on my headphones and ignored them talking to another group. I know I shouldnt have left her and I regret it I want to make it up to her and her mother but it seems that I can't. What should I do with our friendship? Should I make up with her or keep on ignoring her ending our friendship? I still care for her but after breaking my word I don't think I'm worthy enough to be her friend when I basically left her alone

I know where you are coming from but I think you should just stop avoiding her. I feel that a lot of us don't realize how important our friends can be and when one just leaves or avoids us like that it can be very hurtful. She obviously wants to talk to you and still be your friend. By avoiding her and not confronting her, I feel that you are just hurting her a lot more. Sometimes it might seem easier to take the blame and hurt for others but real friends want to be with you no matter what. Just tell her the truth, and why you avoided her and how you feel, I know she would understand. ^.^
