When you're dating someone way younger than you, you might tend to find that the way they act sometimes is a little childish. It may seem non productive to you about the way she is coping, but all you can really do is keep being there without trying to do or say anything that might provoke any negative reaction from her. But it will be up to you to decide whether she is coping from the break up, or if she's just being too darn childish for you to want to handle. I wish you the best of luck to get through this.
