It sounds to me like he said that about you to the preacher because he was trying to cover up his own mistake by tossing you in the fire.
And I'm sorry, but it is cheating what he did. The bible says that even a lustful thought toward anyone but your wife or husband is commiting adultry.If he is just making excuses for what he has done, he's pretty likely to do it again.
Forgive me if this sounds angry, I'm just appaled at the excuses people make for the way they treat others!
