So how should we defend our sovereignty? Of course, it is definitely not advisable to fight back with your boyfriend's mobile phone. The really powerful counterattack is to let her boyfriend take the initiative to reject her. If you find that this girl sends messages to your boyfriend every day, you can have a good talk with your boyfriend and ask them what their relationship is.
Sometimes a boy doesn't understand the magical operation of green tea, so he doesn't know what the purpose of girls often sending him messages is. At this time, you should clearly tell your boyfriend what will happen if you are having an affair with a girl. You can advise your boyfriend to keep a certain distance from this girl, and he must obviously refuse the girl to send messages.
If your boyfriend really loves you, he will be awakened by your hint. If your boyfriend enjoys this kind of ambiguous behavior with girls, then I advise you to change boyfriends as soon as possible! If a boy really loves a girl, he won't look at all the flowers and plants outside, because only you are his only one.
