In those kinds of relationships it is difficult to ask them to stop any contact or friendship because they have been together half of their lives and they have lots of things in common, like their children. Even  though they are adults now, both are part of their life. They must have had a very good loving relationship so it is hard to cut that connection unless you had asked him to do that in the beginning. His ex wife could have manipulated him when she discovered that he was leaving her. Then he couldn't have had any option and as time passed they got used to having a loving friendship. You should talk with him and tell him what are you feeling right now with that relationship, because the only thing that makes it perfectly acceptable to have a close friendship are their children, but they are grow up now. So he needs to think about your feelings but you need to say them.
