Girls are usually angry when they say such words. Even if you explain that it is difficult for them to get in, it doesn't mean that you really don't want to say anything again. At least you should show your care or worry about being misunderstood to let him know that you really care about him.
If so, you should first reflect on yourself! Maybe you have done something that your girlfriend can't forgive. You should learn to make up for this mistake, and if you know that a girl needs to be coaxed, you should tell her that you really won't do it in the future. However, when your girlfriend starts to listen to your explanation, you should not think too much from your own point of view. You should learn to please your girlfriend and say sorry from her point of view, This will make your girlfriend happy and will be able to lean closer to you in the future~
Don't try to reason with girls. Even if you win the reason, you may lose mutual trust or even feelings. In fact, most girls still understand the reason and reason very well, but sometimes they are wayward and act coquettish in front of the people they like! That is, they want to attract the attention of the other party.
