Just to clarify, and no shade meant, but when it comes to evidence he said she said is actually valid evidence. In many trials two people provide opposing testimony and the jury evaluates both and decides who they think is lying and who is more reliable. So saying he said she said is not really valid in a legal context, and when someone says something and then brings receipts in the form of message logs or supplemental evidence it becomes an evidentiary matter, not hearsay.
