My IC told me (who btw is a solution based therapist) that 60% of all problems in a R (be it a marriage, sibling, friendship... whatever type of R you are having) do not have solutions that work for both parties. HOWEVER, using the solutions based theory there is a workable way to not allow the issue be an obstacle for the long term.

Of course this only works if both parties are willing to learn how to do this. Hell, I only have to do it with myself and it is still tough! LOL!
