Hi everyone. I have cut relations with my parents due to several situations. I had cut relations a few times and gave 4 attempts to make amends. The last message they sent me was a threat, so at the time I blocked them. Now they decided to start looking for me. I live in another country. They managed to go to a previous workplace of mine and someone told them enough information to find me. I haven't seen them, but they saw my girlfriend. I don't want any contact, but they managed to get my address. I don't know what to do. They never accepted a no for an answer. Can someone give me some advice on what to do?
