Brother I know it hurts no matter how bad the relationship was I believe part of it is people hate change, and that's a pretty big change. The other part is knowing you will have to start all over again. Go out and make a good single friend, male, not female! Why, because married men don't like single, or about to be single, men around their wives. Don't sit at home! stay busy with something productive. That won't take the pain away, but it lessens the time it persists.
