I too have seen no real tendency toward obsessive compulsive behavior.
I can say that, upon occasion my so does get a bit obsessed about certain things and stays that way until the goal is reached. It all depends on the importance of the goal and it is not exclusively CD related.
For my part I do understand why your ex called it lazer-like focus, because when he does get obsessed, it can sometimes feel like that is all he is thinking and or talking about, even if it’s not. However, to be fair I get that way sometimes too, and honestly probably more often than he does.
In terms of CDing right now there is a very intense focus on perfecting her look with a view to going out publically for the first time. Reine is right intense desire not OCD.
