2. Give gifts. If the apology has no obvious effect, then send a gift! Such as flowers, plush toys, etc. , according to the preferences of girlfriends. Generally speaking, a girl won't refuse. You can invite her to dinner and confess at the dinner table.
3. send text messages. If your girlfriend is angry, doesn't want to see you, or even turns off her phone, you can choose to send a message as soon as possible! As long as she still loves you, she will definitely turn on her mobile phone quietly within an hour to see if there is any message for you.
4. Take the initiative to write a letter of guarantee. As long as the girlfriend says, "What should I do next time?" You should apply for a guarantee or something. Remember, in the content of the guarantee, you must not repeat the story that caused anger. It is completely "seeking death." You just need to repeat that you did something wrong and promise it won't happen again.
