I must stay calm and be solid

These are the most challenging times in my life. Katie is divorcing me because she has been unhappy for 2 years and to top it off she started a physical, emotional relationship with another man even before we divorced. I have been getting help but I also know that I must be calm and solid through out this whole thing, for my kids sake and mine. Katie has made choices and has to live with those consequences. My role is to make sure my kids are safe in every way.
