Grace and Cat probably have great examples, you just have this no biggie attitude and act as if everything is great, but look distracted, text someone when he's around, maybe just wave if you see him, then look away.
It's tough man I know, but what else can we do.
During the BB season for my son, one day got my wife a diet coke and we just talked for a second, like old acquantices, the next day after the game I went to give her a bday card and she says you have to do that now, either way, just smile and go on.
