Sounds like extreme OCD/perfectionism to me! I bet he's the type that likeds everything "just so!"
i'm currently involved with making lots of knit scarves for Christmas & I was just diagnosed with impetigo on my left hand! So I'm feeling out of sorts because knitting is a POSITIVE obsession of mine; I always have it with me in case I have to wait for ANYTHING.
Suggest he get some therapy or at least take an OCD evaluation.
Happy Holidays,
