What's interesting to me is that this is my first marriage, her second. I've always been highly motivated to work on it, her first choice is always to leave when things get tough...in a way, she always leaves emotionally and mentally even if she stayed physically.
She had an unhappy late childhood and adolescence because of a lot of tension and unhappiness between her parents, so always thinks it would've been better for them to divorce.
I lived through the divorce of my parents which occurred shortly before I became a teenager, so lived with and through that pain, remarriages, etc. and have always been against D.
