It is up to that person but attempting to sway them by telling them to switch games isn't helpful! To encourage them is very helpful it can make a lot of progress.
No triggers won't resolve themselves by themselves nothing will, but someone could come along and help him or he could figure it out. You never know in time and saying to start over on a new game will have the same problems. You will problems in everything, why get rid of new problems because of old problems.
