The little and big... made me *think* I know who it is.. if I am correct- then I know from other posts: you have tried talking many times- vented even more, and cried your heart out a time or twenty... Sometimes we have to do what is best for our own sanity- the kids are very resilient, and they honestly would rather a happy single mom, than a sad, angry married mom. The little ones will be fine, and the big kids- well chances are they saw this coming, and know you well enough to know you did not go into this lightly. Keep the bashing to yourself or in small anonymous rants,-- and they will see you as the bigger person in the end
Good luck hun.
