you … to him/her
Laisse-moi faire, tu lui fais peur.
Let me handle this; you're scaring him.

Si tu lui fais du mal, tu me le paieras !
If you hurt him, you'll pay for it!

And you trust him?
Do you see what you're doing to him?
Tu lui fais toujours confiance ?
Do you still trust him?
You're hurting him/her.
