I have been reading these today and am perplexed also.

Is there any event you can think of that occurred about the same time his new attitude began to assert itself?

Do you think that the encounter with XOM may be the root of this latest chapter? It seems to have happen around the same time.

I wonder what was discussed? What was shared ?

It seems your H went down hill after the encounter. Something is brewing. Perhaps WH has checked out and just preparing and waiting the right moment. Very strange.
