The little girl must be still very young. If verbal communication is not possible, tell her via email or text message. That's your job QQ. In order to make your life better, you cannot write such a signature. Also tell her that she should learn a little bit. To see if someone loves you or not, you can't verify it in this way. You love her, and it shows in every aspect of your life. Rather than a signature proving it. There are also men who can tolerate their girlfriend's willfulness, but remember, the premise is that she doesn't go too far. Don't lose yourself for love.
