I had an ex-girlfriend, and we were together for about a year and five months. I didn’t give her enough attention. I rarely called her — I only answered when I felt like it. I know now that I hurt her, even though I truly loved and cared about her. I was careless and distant. She made a mistake once, but she admitted it. Instead of understanding her, I told her we should break up and that I didn’t want to talk anymore. She cried and kept texting me, but I ignored her. Now I really miss her — even her small habits, her ጭቅጭቅ moments. A month ago, I texted her, and she replied, but I didn’t respond. I miss her deeply, and I regret how I acted. I want to change my attitude if I ever get another chance with her. What do you think I should do?
