I think you were being childish and judgmental and should apologize. You could have simply blocked his status and moved on with your life. You may claim you didn't mean negatively, but telling someone what they should or should not put on their Facebook is ridiculous.
You may find his comments unhealthy, when in reality you don't truly know what goes on in their relationship. He may just be bored and have nothing else to write.
Just delete him off your page.
Cops are wonderful assessment tools at a HazMat incident.
Send them in with a lit road flare.
If they don't pass out or blow up, it's safe.
