It is said that fire prevention, theft prevention and girlfriends prevention, so how should we guard against it?

I think you should mind your own mouth first. A best friend is a best friend, a boyfriend is a boyfriend, and a man's heart is separated from his belly, a woman's heart, and a needle in the sea. What he says doesn't mean what he thinks.

don't always show your love in front of your best friend. Don't always show off your boyfriend. Once she starts to think about your boyfriend, you will not be far from tragedy. No matter how dutiful your best friend is, she can't stand you gossiping and showing off your boyfriend thousands of times, and when she seduces your boyfriend, you may still be kept in the dark.

don't travel with three people on a date. If you create too many opportunities for them to be together, they may be more likely to turn you into an audience. Don't let them get along alone. Well, as long as you're not stupid, don't let your boyfriend always be someone else's free labor.

I won't always turn the topic around my boyfriend in front of my best friend, and I won't show my love from time to time. When talking about the other half, I will take an understatement and turn the topic to other topics of interest. Your best friend is your playmate and the person in your life circle. There is no need to involve your boyfriend.
