Mommy22,
I am on your hubby's end... but I'm telling you now, my wife was so incredibly guilt stricken by NOT telling me. I feel hurt, I'm angry, and I've also had thoughts of suicide. But its better she told me.
This way we're not avoiding the issues at the root cause of our problems that caused this issue to begin with. I have addressed my own issues, and still have a little more work to go on myself. I honestly feel that this is a one way battle to save our marriage and that I may be loosing. The only thing that is going to help is time.
You have to tell him. Otherwise, its going to consume you with guilt. Just like my Jane. If you would like to talk, send me an IM.
*edit*
And so you know what I am talking about.... this is my story.
Very complicated... please help
