We broke up and texted my girlfriend, but she only answered one or two words, what should I do?

Be a man, be responsible, and don’t talk about breaking up casually. In this situation, do you want to get back together or are you expressing your regrets? If it’s the latter, then wish her no more in the future. Contacted her. If it's the former, first resist your man's responsibility, think about it before approaching her, and see if she will forgive you. If you don't take your responsibility, I suggest you stop disturbing her.
