Can my husband get in trouble for breaking confidentiality?

Something I didn't know about my husband for the longest time is that he used to be a priest. He got ex-communicated because he broke confidentiality. Someone had admitted to SAing a child and seemed very adamant that they were going to do it again and he could not convince them to turn themselves in. So he did and got in trouble for it. He felt like he was treated worse than the actual pedophile so he just religion completely because he thinks a lot of churches are corrupt. Looking at him you could never tell he was a priest before. He's tatted up. We were back in the town he grew up in recently and he got recognized by someone. They said hi but then started saying some kind of rude stuff about my husband's appearance and how they can't believe he was once a man of God. We started to talk away and this person followed to continue talking and kept making these snide comments about my husband's appearance so my husband said "Did you ever tell your wife you cheated on her." The person stopped talking and my husband said he broke confidentiality in the past. He's not Catholic anymore. He's not tied to the seal of confidentiality. He remembers a lot of peoples confessions in confessionals so if they all want to stir the pot he'll make it boil. The person left. I don't know how serious my husband was. He may have just wanted that person to go away but can he get in trouble for that? Everything I looked up only mention him getting in trouble with the church and he's not apart of the church anymore.
