My cousin's brother-in-law often sends me messages, but I never reply to him or pay attention to him because I hate people like him. Maybe he sent me a message.

If your cousin goes too far, you should consider yourself a victim, and don't defend yourself just to protect your loved ones, because at that time, you don't know what bad rumors will come out. Also, make it clear to your cousins in person. Be sure to face it, and it is best to call someone you can trust to avoid being at a loss. Remind me to harass you behind your back and expose him in front of relatives and friends. Besides, don't be silent, the wicked like to bully honest people. But because you didn't reply to the warning, your cousin took it as your default acceptance, and she retorted that you didn't refuse.
