Oh, I know you do! I used to as well. It hurts to break this comfortable routine because it is so safe and because it feels like you have a piece of your old life back. But ask yourself, do you really have it back or are you scavenging for crumbs? Getting a life means not being your WAS's placeholder until someone more exciting calls.
Watch TV without her. Take yourself to the movies. Buy an audio book and go for a scenic ride. You need to learn about all the things you like doing alone and realize that your own company is enough. Then you need to learn to have a good time with people who are not your wife: your children, your family, old friends, co-workers. Heck, go out and make new friends. Try meetup.com. You can find groups of people who go out and do things together based on joint interests.
The point is that you need to live and you need to stop gifting your life to your WAS.
