Occy01, great job leaving the situation without confronting. not an expert by any means but likely would not have been productive at that point.
Certainly understand the range of emotions being experienced (my sitch is similar). I struggle myself with moving back forth between compassion - because WAW must be sad, hurting, depressed, angry, etc.... even if they are not able to show it - and angry about the fact that they don't seem to see enough value in trying to work things out.....
Posting here is good therapy and sounds like you are making the best of a bad situation....
