It's okay to think about meeting the ow, but I strong advise against it. Why? The ow will tattle on you to your h and it may make things worse between the two of your right now. The best thing to do is sit quietly and keep the focus on you and your children. There's absolutely nothing you can do to help him.
One more thing, keep an eye on your finances, checking and savings account and the credit cards. Make sure that your bills are paid because mlcers do tend to forget to pay them. Do not rely on him for anything at this time because he's unpredictable.
Keep the focus on you and your children!
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.
