Dear asamanthinketh, I understand they way you may feel. If inside you feel much pain you are so loved by God anyway. When people tells you to not dwell on the past is because sometimes the past can stick us, give us much pain and it doesn't allow us to enjoy the future in God's freedom. I know that it may be hard to forget and to forgive, but think of what God did to all of us.. He decided to forgive also those who put Him on the cross.. Isn't His love amazing? In the same way God want us to forgive who did something to us. And trust me it will be helpfull for you! I don't think you want to suffer anymore. Please consider what i'm telling you. A hug from italy
