I don't think there is anything wrong with journaling about your observations Ciluzen, it is quite interesting actually. Your first point resonated with me, I also find that my H is struggling to look at me and I get very little eye contact, and more sideways looks, maybe it's to do with guilt? Who knows, like you said I don't want to get into mind reading or guessing.
I'm glad you and your daughter had a good time
I hope your "thoughtful" state of mind help can continue, we learn so much through reflection...
Take care xxx
