Is it illegal to send anonymous text messages telling each other that cheating leads to divorce?

If it is true, it is not illegal. If it is fabricated, it will bear legal responsibility.

Please don't send text messages until you confirm. If it is true, you can gently remind me.

Spouses can apply for divorce if they find that the person next to them is having an affair through SMS, but as evidence of adultery, it is more difficult. Legally, the so-called adultery refers to a married person having sex with a non-spouse, which is difficult to prove only by the content of mobile phone text messages.
