Today, my girlfriend drove me and her younger sister (7 year old) to Walmart. I bought her sister a toy. She wanted me to buy her a Jewelry Box. She had a Jewelry Box look just like that, but it had been stolen. She wanted me to buy it for her. Because I thought it would remind her about her ex, I said I would not buy it. She got mad at me. I paid for her sister's toy, and she paid for her Jewelry Box. After check out, she told me that she would not drive me home. Therefore, I went back into Walmart, and walked to home from another door at store. It rained outside. She called me, but I did not pick up my phone. When I got home, I opened my message. My friend said my girlfriend had an accident. I called my girlfriend back. She told that she go around to find me, so that why she got accident. She and her sis were fine, but the car was not. By the way, she was the person fault for the accident.
I drove back, but someone else already drove her home. I just saw her car have been push. Now, she wants to break up with me. What should I do now? I feel so regret.
