Coly - while it's great that he's willing to come when invited, I guess my question is: what would he do if you did not initiate contact at all? And what would you do/how would you react?
My guess is he would stumble around in the dark and figure things out. Same as you would do. I think you may both need that.
If I may do so, you perhaps think you're growing closer but until you see what he does when not invited, you don't really know that.
Wishing you all the best in 2017!!
