Well, I'm so speechless. It doesn't matter what you tell him if he's unrepentant. I think you should confront him and talk about it. Fine, he's heckler, and so what?

You don't have any choice than to let him know what you observed and how you feel. Truly, you love this man? Cover yourself in tears, he'll definitely be remorseful and pray he changes. The assertion "The only woman who is 100% sure of where her Man is every night is only a widow" is true after all.
