Lou I'm sorry your struggling, it's completely normal to have the feelings & emotions that your experiencing and it's all part of the healing process - it's very painful but try to keep in mind that every minute of pain moves you a little closer to coming out of this happier & stronger (you will, I promise!).
DB is for YOU, yes saving your marriage is a possible bonus but ultimately it's about saving yourself whilst going through a very very tough time - you really do need a good support network around you that can help you through this, why don't you feel comfortable telling your close friends/family about your situation? It really would help?
