I think there are lot of similarities in various cases. My H is definitely a low energy MLC'er. He was at home three years from the start of his MLC. He moved out, but continues to be very low energy through the tunnel. Spends most of his time alone, rarely finishes any projects, major workaholic, and focuses on athletic training.
For the majority of his time at home, he was angry and acted irritated towards me. He still ate dinner at the table with our children and we went to school/church functions together. At home, there was only conversation that I initiated and even then, it was clear he was quite uninterested in anything I had to say. There has been no affection of any kind in years.
Now, however, he seems much less angry, even sounding like his "old self" during many conversations. He doesn't avoid me at every opportunity, though he doesn't seek me out either. Most interaction is through text/email.
