What's wrong with girls talking and cursing? When a girl is chatting, what she says is totally different from what she thinks inside. The most common phenomenon: a girl is respectful to you and very polite when talking to you. Maybe she hates you in her heart, but only smiles at you out of politeness. If a girl scolds you when chatting, it shows that she has fallen in love with you.
But she is often fierce to you, yelling your nickname and cursing at you. This does not mean that she doesn't respect you, but that she feels that she has a good relationship with you and doesn't need to be too outspoken. So you are the most real side. The more she loves you, the more she believes you belong to her. You can feel your intimacy from words.
Don't care about the girls' three dirty words in the chat. Each of them shows that she loves you very much. The more she scolds you, the happier you will be, and the happier you will be.
