Ok, so you want to find out what it would be like to get back together? Try it. There's no harm is giving it a solid try, especially if your H is working on recovery. Now, if you are worried about how the kids will react to the changes, don't try it. Give it more time. Either way, you won't know until you do something what the outcome will be.
Have you talked with your husband about all this? How does he feel about a future with or without you and the kids?
