You may never know if H told the mutual friend MF the truth or not.
I think waywards try on attitudes and make statements to see the effect of them.
If I were you then I would just act as if he had said nothing to MF. In your interactions with MF then you could choose to validate, apologise that MF was put in the position and act as if H had not said what he did.
