No. If he has an issue it would be more like Obsessive Compulsive Personality Disorder. That type of person can have hoarding issues, is not great with emotion (understatement), and really really does not want new ideas.

But I would not want to diagnose from a distance.

It could be the extreme stress from covid/lockdowns, doesn't mean he has a full-on personality disorder otherwise.

They could also be just really incompatible, seeing that TishaBuv likes ideas and this guy seems to be really triggered by them, liking to stick to his plans. Which is completely not TishaBuv's fault, it's totally valid to like ideas and stuff, it would just be an incompatibility between them.

On top of the incompatibility he could have *traits* of OCPD, but doesn't have to have the full personality disorder. Again, diagnosing when we are not qualified psychiatrists or clinical psychologists is not a good idea.
