I hit my girlfriend's sister-in-law. What should I do? She said she was breaking up!

You handled this matter a little too much, and almost kicked the girl's nose flat. It's normal that your girlfriend is really afraid of you and even thinks you are a little cruel. After drinking, she will go crazy, which will make her unable to control you in the future and will only keep her away from you. What you can do now is to apologize to your girlfriend and say to her, "honey, I'm sorry, I know you have a strong reaction to what I did, and I know what you think, but I will never do anything to my dear." Don't worry, because of this, I know it's a bit too much, and I will definitely change it in the future. I was so impulsive that I didn't know it was my sister-in-law. She was a little too advocating that day. I can't breathe either, but please give me a chance. Sister-in-law, can't I apologize to her? I will take care of her. Please don't affect our feelings, okay? " Buy some condolences, sincerely apologize to your sister-in-law, take your sister-in-law to check if there are any serious problems, pay medical expenses to make up for your cruelty, and spend money to eliminate disasters. Do these things, don't be afraid of losing face, take a step back calmly for a while, just to let your girlfriend see your sincerity in correcting. If you can't forgive you after all these things, you can only accept the reality of breaking up.
