I've had a cold war with my boyfriend for several days. He sent a message today saying that I miss you. What should I do?

The most taboo in falling in love is the cold war. After a long time, your heart will get cold. Think about your previous relationship and see if you still love him. If you love him, don't continue the cold war because of small friction. He gave you his information, which means that he chose to bow to you and apologize. Forget the past. When it doesn't happen, get along well and give him back information, just like before the cold war.
