I am sorry that you are here, but glad that you found this place. It has helped me a lot. Read HUFI's thread that was bumped. Look in the Healing Library here. These threads and bits of advice are sometimes easier to get through than a book.
I know the feeling of just giving up on your marriage. When everything you think is happening to you is wrong. I wish I would have had the courage to drag myself into IC and my BW into MC before it got too bad. You are not alone.
Use this to fix yourself. Figure out how you need to fulfill that need for communication and intimacy.
Hang in there.
