I am friends with me ex. If we didn't have children, we would never see each other. As for dating, I see no need to discuss any of that with her. Sort of like my parents, I didn't feel the need to let them know I was going out with someone. If I was to become serious with someone, she would know because our children would be involved. And actually, if you are really ready to move on (and I use move on to mean dating), his art and his books really wouldn't matter.
