The boy introduced by my friend turned out to be a scumbag after being fucked for a long time. And she knows it all. He only confessed to me after we broke up. How should I deal with this when he comes to ask me out to play on a regular basis?

Don’t trust her in the future. It’s clear that the boy is really not a good character. She introduced him to you and doesn’t treat you as a friend at all. What’s the point of her intentions? Want to see your joke? In the future, there will be less contact and less contact with this kind of friends, as long as they look good on the surface. If she usually asks you to hang out, you can find an excuse to refuse, don't be embarrassed.
