Matched with a guy on online dating and have been texting and calling for 3 days. I looked up his full name and seen an article from years ago that he stalked and ex after she ended the relationship. I’ve have ended the chat with him and said I’m not dating right now due to personal circumstances, he took this well and we said parting words. I am so worried it’s making me sick that he’s going to hound me with messages or worse find out where I live or work. He knows what town I live in and my occupation but doesn’t have personal or work address. I haven’t blocked him yet but should I? Please help
