You know everyone is just trying to help you. We wouldn't want you to give up even if you felt your marriage is over. We all feel our marriages are over at one time or another. Instead of going dark and what you need to do is just let go. Let go of all the hurt. Let go of all the comments he has made and everything he has said to you. Think back to happy times. Until you can let go of all of the hurt, you can't heal. You must heal yourself before you can even think to heal your marriage.
Try not to think about what your H is doing. It is hard but when you don't know, it makes life easier. Once you learn to let go and live your life, things start to look better. I know everyone tells you that you are a strong woman and I am sure right now you don't feel that way. That is ok, not everyone can be strong all the time.
No one here is trying to make you out to be the bad guy. You need to stop focusing on the past and start living in the present. Don't even look to the future. You say your H keeps bringing up your little indescretion, well next time he does just ignore him and change the subject. Actually, don't even talk about your relationship with him.
