My best friend's boyfriend always likes to chat with me.

It's really a headache If you tell your best friend, whether it's the man's fault or not, her cognition must be that you seduced his husband first. Even if you are innocent, she will think there is something between you. I think, if I were you, I might take an indifferent attitude. In addition, tell her husband by innuendo that if he goes on like this, you will get a larger foe and scare him first. Look at his attitude.

PS: You can also use that. You can pretend that you don't understand anything he sends. To put it bluntly, you are playing dumb. When you don't see it, you can play as usual. But every time I go out, I have to hold my best friend.
