A quick note - traveling - keep on keeping off the pressure - do not confront or push back - he (I think I am similar) wants to get closer but is afraid of your bite. Perhaps some John Gottmann (not sure name) would be helpful - he talks about marriages with one conflict avoider and one non avoider - observe when he pulls back and then do not do what you did that lead to that...
Home tomorrow and it is a holiday there so I will still be sporadic - hang in there - later - Luke
