I have been divorced too, but I've kept mine. I love all things history and was so grateful to my Mum when we cleared her house, for all the birth / marriage / death certificates, labelled photos and and other artifacts that recorded our family history. The emotion they may stir in you, will not be the same for them, but I am sure your grandchildren and even your great-grandchildren will have fun piecing together past years of your family, and learning what great-great-granny looked like.
One piece of advise I would give - that you label all the photos on the back with the the names of those who appear in each photo. You may know who they are, but future generations may not.
