My xh acted as if I were acutely infectious were he to come within about 4 yards of me, for about 5 years. I once sat on the other end of a very large sofa, and he got up and moved away at once. Ideally he preferred not to be in the same room. I couldn't hand him a beverage, but had to put it down and then he would come and pick it up.
It was so strange. Now he tries to hug me if we meet (yes this is the same man who is suing me) Not that we meet often - the last time was sometime in January/February 2013. We occasionally speak on the phone, but I try not to take his calls. He never ever leaves messages
Oh and during the middle of all this 2006 or 2007 we went out to dinner to discuss divorce and he started feeding me his dessert off a spoon. He never normally did that kind of thing. Maybe he felt safe in a public place
