I looked up the dictionary for "fall out". It means to have a fight with someone and then stop being friendly and stop talking to that person.
Sometimes, people tell you that they are not talking to you. For example, you have a spat with your girlfriend, and then she tells you she is not talking to you for 4 days.
Children also say this when you upset them.
I want to know what is the expression that can be used for this situation?
Example: Girlfriend to boyfriend: Why did you forget my gift? I am falling out with you for a week. Please don't beg.
I know that fall out doesn't work. I know she can say I'm not talking to you.
But is there an idiom or expression that can be used for that situation?
