My boyfriend broke up with me and deleted my button, but I think why didn't he change his signature? His signature just wants to know your thoughts.
Your boyfriend broke up with you, which means he wants to break up with you. It's his decision, and he deleted your QQ, which means he doesn't want to have anything to do with you anymore. If he still loves you, he won't be so determined. Give it up. Holding that little fantasy is the most hurtful thing.
