SA, I firmly believe they face their issues or the destruction that have created. You have to remember, these are people who have not "owned" their issues. Many of them are conflict avoiders/passive/agressive individuals. Very seldom will they admit that they've done something wrong and it will always be the other parties' fault.
Bottom line, no marriage is going to be perfect. There are always going to be some issues that crop up, but most of these issues can be resolved if both parties work together. The mlcers can't justify why they left us, so they come up with petty things, i.e., just like kids.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
