I feel a little sad after reading your question. I don't know how long you've been well. It would be a pity if it took a long time. I don't know why you broke up. Is it a fight? Otherwise! Just because you say your girlfriend's signature hasn't changed doesn't mean she still has you in her heart. Maybe she doesn't care about changing her signature! You can see what she said on QQ or WeChat. Generally speaking, boys are more likely to get out of the world of love, but girls may take love more seriously. It is possible that when they just broke up, they will still have you in their hearts. Maybe she will find a man to forget you slowly! If you still want to be with your ex-girlfriend, you can also try to regret one thing, pursue your ex-girlfriend again and say that you did something wrong, but you still like her as before. I believe your girlfriend will forgive you. If it takes a long time, you may really not find a girlfriend. You should think clearly! I read your question, and you may still have him in your heart. Isn't it! Otherwise, I wouldn't ask such a question for no reason!
