What do you do when you have moved on and your ex hasn't but you have a child together?

* Each individual develops at their own pace. If you have joint custody of your child then try to just remain friends even though you ex has not moved on. Let your ex know that it's over and feel free to date again. You are now each taking separate roads and he has to learn to stand on his own two feet. It is nature for some people to cling onto someone that they feel comfortable with and dislike change.
