D.P.
Honestly her mate and your BF sound very similar!
Here's a big newsflash for those women who haven't realized it yet: MEN HATE DRAMA. It's their nature.
AND: Women nit-pick and over-analyze everything. It's our nature.
My husband does not get drama from me over things we discuss. I do not control him and he doesn't control me. Yes, we both have responsibilities that we are well aware of and fulfill, but it's not a "you HAVE to do this" kind of thing. We also trust each other and respect each other.
Example: If he goes somewhere (a guys night out) I don't DRILL him about every detail of the evening. Usually I ask him how Bob is doing, did he have fun....and he responds. I don't have jealousy to drive my questions, and b/c I trust him I really don't care if there was a topless blonde sitting next to him at the bar! LOL
So, while it may be "typical male behavior" in response to an insecure, jealous and/or controlling wife, it's not typical behavior in my house.
I think the better a relationship is (i.e. less control, jealousy, distrust, insecurity) the more openly and freely a man will communicate. Not yours, specifically, just speaking in general.
Again--they hate DRAMA!
