Thing is, I don't particularly care to conceal my feelings about this person. If she finds out I would be willing to trash her, I'd at least be happy with the knowledge that the truth is out there.
I guess I hate subterfuge.
I didn't hear the argument and I'm not sure I'm following everything, but going just by what you describe it sounds to me like you're right in the policy you advocate about either telling someone directly or not saying anything, but perhaps the way you said it made your husband a bit defensive and he's taking what you said differently than you meant it, which is what it sounds like he's reacting to. Again I didn't hear the conversation so this could be way off, but that's what I'm picking up from what you describe.
