Why is your Ex-friend an Ex-friend?

Back in highschool, I cut three friends out of my life because I found out they were only friends with me for my money. I'll call them A, B, and C. A and B were my best friends and I wasn't too close to C but C was their friend before I joined the group, so we hung out together. A and C came from poor families that lived on welfare. I'm not sure if B's family was on welfare but they had too many kids and not enough resources so they struggled. They didn't have a good home life. It was always messy and hectic, with little to no parenting. My home life wasn't the best either but it was nothing compared to them. My family was a comfortable middle class and we lived in the nice neighborhood of the town while they lived in more run-down part of the town. Anyways, it never occured to me that I was always paying for snacks and other small stuff and how they borrowed things and money from me all the time but forgot to give back. I have ADD and am extremely forgetful so I almost always never remembered exactly what or how much I lent and if someone told me they paid me back and I had no recollection of it, I just blamed it on my bad memory. I was an extremely socially awkward, ugly kid that has hard time fitting in and was happy to have friends at all. I considered them my best friends. I learned their true colours when my family had to move to a different town. I asked them to return all my borrowed stuff and money and they kept forgetting to bring them and made excuses. Some random kid at school came and told me how my friends constantly made fun of me behind my back and bragged about stealing money from my wallet everyday. This kid didn't have the heart to tell me this before but felt the need to tell me the truth before I moved away. I shared locker with friend A for two years and apparently A was going through my wallet and stealing money everyday, just enough so that I wouldn't notice. When I comfronted them about it, A admitted it and looked shameful and told me she planned on paying me back one day. B apparently wasn't part of this but knew about everything and didn't wanna take sides. A and B returned some of my stuff back but it was C that owed me most of the money and items. C flat out refused to give me anything back at all and laughed at my stupidity for trusting them, mocked me for being a spoiled little rich kid, and ridiculed me for everything(I was ugly, I had a nasty body, nobody liked me, nobody would want to be my friend, no one would ever wanna date me, I was a loser, etc). When I told C that I would call the cops if my money and stuff are not returned, she told me if I do, she will send someone after me to teach me a leason, and besides, cops wouldn't do anything about something small like this. So I moved away, dejected. A and B wanted to stay friends and keep in contact but I felt so betrayed that I wanted nothing to do with any of them. Years later in another town, I ran into A at a Chinese restaurant. I was a customer and A was a server. A came up and told me how sorry she was and she still plan on paying me back one day. I just sorta said 'yea, you do that.' and walked away.
