I agree with ALF.

This is something you and I have both struggled with recently. This is your chance to show him you are willing to move on without him, even if its a slight façade. This is another chance at the mystery on his part, but your doing it for yourself.

We never know if and when our spouses will "snap out of it", but I read a quote on here yesterday somewhere. One of the things a spouse needs to have is that feeling of losing something real and tangible. What better way of doing that than showing him your ready to do that, and its much harder to do that from a distance. Stay strong, stay positive, and try to let go of the feelings that you need to get away from him, just get away.
