Almondeyes hit the nail right on the head. Friends are all well and good, but if they don't respect boundaries of decency, they're friends who will quickly become enemies while causing friction between you and your husband.
If you approach yor husband, who no doubt appreciates the flattering attention (I certainly would), you can bet on offending him because he believes he's "stronger" than you give him credit.
The absolute worst position to be in is the jealous spouse with others showing such adoring admiration to your husband. It has to stop and your friends, if they're your friends at all, have to respect the boundaries of marriage.
From a husband's perspective, never tell your friends of your husband's shortcomings. He's already aware of them and he knows that you are too. You know because he lets you into a part of his life that nobody else sees - his vulnerabilities and limitations.
Former Congressman Bob McEwen and his wife Liz once gave a talk they called, "Love, Respect and the M-1 Tank". Among other things, Bob likened a man to the M-1 Tank, used by the Army. It goes out into the world rugged, tough and hard charging. Bullets bounce off of its tough skin. The enemy even with a machine gun can't harm it.
On the inside, however, the M-1 Tank is a very sensitive machine. Only the most trusted people get to be inside that tank - the Soldier who wears the appropriate uniform. If that Soldier starts swinging his elbows and breaking stuff, he gets pushed out and is never trusted inside again.
According to Bob McEwen (and I agree), men are a lot like that. We go out into the world of work with our game face on, take a hail of fire and abuse all day and it just bounces off. When we get home, our wife, the one we trust with our more sensitive side, is the one and only person who can do a lot of damage with words, especially to others about or limitations.
Is it stupid and macho? Maybe. Honest? Definitely.
It may help just to constantly tell your friends how much you and your husband mean to each other. Talk to them about the better things you do for each other.
Best wishes,
Rob
