I understand how you might be slightly uncomfortable with the situation. But in all honesty, I would do it for the kids. Its still their family, you'll always be tied to them because of that relationship. There is no reason you all cant get along.
If theres anything you can do for the kids, keep this routine as long as you can for their sake. Family is family, help them understand that even thou things arent working out for you and hubby. They will still be a part of their lives.
