In my opinion there is no "confrontation" unless you are ready to start the D process. Why? Because like Cadet says, he won't listen. So, anytime you do confront, without any serious follow up consequences, you lose a little bit of power and credibility.
Better to accept what is, (remind yourself it won't always be that way) and take steps to make it work for you. Remember, a true MLC usually takes YEARS to play out. Having said that, I believe most will come out better people in the end, and will realize who was there for them while they were off and running.
The real question is will you still care or be there when this happens. Your choice, and you don't have to decide today.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
