My friends dont want to talk with me anymore

I have a few friends but they dont want to talk anymore. In school I copied their answers on homework and told them this is what friends are for. I also asked them to lend me money but then they would ask me to pay it back but I told them I would pay them back if they were strangers but that friends should be more understanding of each other. They also told me a few secrets and I said they could trust me then I told other people at school and thats how rumors got started, and my friends came back and asked me if I said anything and how everyone found out but I just said it wasnt me and it was probably someone else. Friends are for having fun and Im having fun and I dont know why theyre acting all weird with me now.
