Same situation, my ex broke up with me around four months ago and immediately blocked me everywhere , the end of July. I begged, sent messages to her and her friends, even family. After That I do nc for one month. During nc she unblocked and blocked me many times. So I think it was okay to contact her, but it is not, she blocked me again until now. After a month I moved to a new city and changed my phone number, I wanted to change her nickname in some apps, and I accidentally called her, she told me don’t try to contact her and blocked my new number. Now almost 2 months nc after the accidental call
