Hi mebefree,

It is so good that you are in counseling now with your DH. Mother's Day is not going to be easy so I guess it's good to prepare. I would advise you to not be attached to a specific outcome you envision. These things take time and don't expect your DH to change quickly since he has just learned what has been going on his entire life is not exactly what he thought. There are great tools here for reducing conflict that you and he can learn and practice, maybe even before Sunday
Here are a few links to tools that hopefully can help you both:
TOOLS: S.E.T. - Support, Empathy and TruthBOUNDARIES: Upholding our values and independenceArguing - don't engageWe can help you here with determining what level of contact is going to work for you and your DH.
How is all this impacting your Sons at this point? Will they be at the lunch on Sunday?
Do you have much contact or friendship or support with your in laws (his sibs and their spouses/kids) these days?
