Enjoy your liberation from stopping someone take advantage of you. He acted offended when you enforced your boundary and stopped letting him use you. That’s what users do. They try to make you feel guilty, like you are the bad guy, when it is them. This will be lonely at first and he may try to lure you back in. Be strong. You are not negative energy. You are a freed soul. You’ll soon feel stronger and go find new, quality people.
