Irish, you are such an awesome dad!!! Every time I read about your talks and activities with your Ds it makes me cry. I'm so sorry they are hurting so much. Thank goodness they have you as their rock through all of this. They are so young and shouldn't have to be dealing with this kind of thing, bless them.
It is interesting what you say about your W having turned into her mum. I have been thinking the same about my H just lately, how he has 'reverted to type'. His parents have both been very cold and standoffish as parents and grandparents. They don't even visit our children on their birthdays and Christmas. Just not interested and have always cared more about their friends and drinking than their children and family. My H always hated how they were, yet now it seems he is doing exactly the same.
Hope you enjoy the safari drive, it sounds incredible! We have nothing like that here. Have fun!
