Oh man. Am I supposed to be the peacemaker or what? Both of you gotta try and listen to each other. For starters, A, stop trying to talk to her in a way as if you are scolding her. And B, please try to hear what he is saying before you shut him out.
Okay, you may be right when you say he is totally trying to critise your every move, but you need to calm down and rethink your actions. Was whatever he said true?
B, TALK TO HER NICELY. And if she shuts you out, wait for for to calm down then s-l-o-w-l-y tell her to see your way, which I expect, is the
correct one.
Sigh. Life would be easier if we were all carebears.
