My boyfriend stopped sending messages slowly, but he was still very kind to me in reality. Why?

Because after the love period, boys will not contact girls from time to time as before, and they will not contact if nothing happens. That doesn't mean they don't respect you. Only after the relationship between men and women is stable, boys spend more energy on work and life, but when they are together, they still care about their girlfriends, which shows that you are still his most important position.
