LL, it seems your H simply has to come to a place where he's ready to truly talk about your R. Thing is, my W has done a lot of self-evaluation and has a significant mindshift as a result of all this crap...an awakening so to speak. I do not think your H has come to this point yet. Why? Who knows. Maybe it's because he really doesn't think there's anything wrong...and that this is "normal." Maybe it's because he didn't "really" go off the deep end and have a full-blown PA...something that might have leant some insight. Maybe not enough time has gone by for him to seek his answers. Or, maybe he's seeking his answers internally and just not sharing. Fact is, it's a process all of our WASes go through. He could just be slow...
Have you really considered "pushing" a little more to go to C? I know you mentioned it to him, but what about pushing? Or pushing to read a book or two? Or possibly, just decide to give it another three months, then see where you stand then. Might it help just to draw a line in the sand and say "in three months if I don't meet X, Y, and Z goals, then I'm going to push?" Just throwing some stuff out there, LL.
