I think its because the pressure is off of him. Does that make sense. Now that you said it was over, he can stop "feeling" all the things he didnt want to feel or not feel anymore. Maybe he feels like by calling it quits, it wiped his slate clean. Now he can start over? I am not sure..just pulling out straws here...take it as it is now, but keep moving forward with your life. The more you move in a different direction the better things could get!
