Angie sorry you have not gotten too many responses on your thread in newcomers, although I just read a few posts right now.
You are still on moderation I think and you need to keep posting to get off of it. Once you are off moderation you will get more responses because your thread will be closer to the top. Counterintuitive of course, but that is also a lesson in DB.
There is hope for you. There can always be HOPE but not EXPECTATIONS.
It sounds like you have a real mess on your hands.
So you had an affair. Is that still ongoing? Do you know why you had that behavior?
You can only FIX your portion of this. After that it is going to be up to your husband to FIX his portion, so that you can rebuild your marriage.
You need to FIX you - whether your marriage survives or not.
I think that is where you need to start to work!
Can you make a list and set some short term and long term goals?
Have you read DB/DR?
Keep posting, post on other threads, and you will get more advice that way.
