Will the police check whether to send cheating text messages on their behalf?

It is not a criminal case, and the public security will not assist in the investigation of short messages. To catch cheating, the first thing is electronic evidence. For example, SMS records of spouses and affair objects, WeChat chat records, etc. Considering the particularity of electronic evidence, in order to ensure its probative power, it is best to entrust a notarization institution to notarize it in time.
