Let's just say women like to do all the talking.
We stumbled upon some interesting research at One Plus One, a UK relationships and marriage site. Apparently, in one study, when couples attended a pre-marriage communication course in an attempt to quell marital distress in future years, men benefited from the class and had less stress in later years. The women, however, seemed to experience the opposite: When wives learned to communicate better, it increased the likelihood of distress for both parties.
And here's the fascinating piece of the puzzle: When men's communication improved, women showed even more stress. Turns out, when husbands talk, wives demonstrate increased conflict avoidance.
Bottom line: Women like to do the talking. Sorry guys, but it looks like you're going to have to pick your battles...
