After breaking up, she blacked me out, and she often updated her circle of friends, but why hasn't the signature I regret changed for almost a year?
Now that we have broken up, let him do whatever he wants. As long as it doesn't infringe on your right to portrait and privacy. Otherwise, we can take legal measures. Live the life you deserve. It is best to find a lifelong partner as soon as possible. Besides, he may leave your signature as a souvenir. If you want to blackmail you, you can solve it through law.
