Hi Karen~ WOW I see your interaction as very positive.
I think it also speaks volumes as to what he is/has been wanting. I see this as his request for space, but he is definatly feeling the "cold shoulder".
Take his que to mean he is appreciative of the space, but perhaps your body language and lack of eye contact are sending the wrong message?
You can still limit your contact or conversations, but when you do pass each other, a smile while making eye contact might be a good thing?
Just my thoughts...
Sounds like you have a good weekend planned. Focus on YOU and have a good weekend.
