I totally agree with those who advise communication in a non heated fashion.. still this often is not easily achieved if you feel hurt. sometimes every discussion ends in an argument. If thats the case for me it´s easier in writing... I can write down everything I want to say without beeing interupted, there is no chance that I angryly let something slip that I would not really want to say.. And it gives the Partner time to think about this first.. He has to read the whole of your opinion and it can sink in a little.. Even if he is of another opinion..she will perhaps at least come to understand your point of view.

But even if this might be a help it never replaces a discussion afterwards.. you really need to talk, just keep it low. ;-)
Hope you´ll be fine
