Sunny I think that Grit has given you some good advice.

The thing about being hurt and foregiving, I will just say that you need to get past that. Because like Grit says your old marriage is dead.
Even if you get divorced and find someone new, you will have to start from scratch.
That HURT will still be there, it is not going to go away because of a piece of paper.
You are going to have to LEARN to trust again and build your R.
My feelings about this are that why shouldn't it be with the same person. Its the same work.

Also detachment is still KEY in all of this.
If that hurt is still there, then you have not yet learned complete detachment. You must learn it to complete the journey. Whether with this husband or another one.

Are your ready to face this yet?
