If You're Serving Another Samson Brother As A Silas, Are You Obligated To Follow Up?

Here's the situation:

If you're serving another man as his Silas and his sinful behavior(s) is continuing to incur tangible, long-term collateral damage to his spouse (her health, their finances), you must pressure him to come clean to her.

Why?

Because she's being hurt unknowingly by his ongoing stupidity.  To be more specific, she might end up with an STD (due to him inserting his wiener into illicit orifices) or bankrupt (due to him racking up debt in light of his secret passion for phone sex, virtual strip shows, hookers, etc.).

This is the primary differentiator between being a Silas and a counselor / therapist.  In fact, you can even go so far as literally looping his wife in (regarding her man's ongoing stupid), though I don't recommend it.  

-------------------------

Her reaction (towards him) to his coming clean may very well (& very quickly) dismantle your friendship with your Silee (triangulated blame), but at least you did the right thing by protecting either or both her physical / financial health.

Silence may very well then ensue between you and your Silee.  

And no, you're under no obligation to follow-up with him.  Instead, if you so choose, simply move on.
