I do tend to be a little too blunt at times. It's just that you are bringing more hurt to both OW and yourself by keeping even a friendship going.
Don't think I don't have sympathy. I know how it feels to have a spouse ignore or harp at you. I also know how good it feels when somebody else pays attention. I just don't think you can have it both ways. If your decision is to stay with W, then you need to stay completely and totally away from OW and make her NO part of the equation. You need to concentrate only on what you can do to improve the R and communications with your W.
Sorry it's so rough right now. I hope I didn't sound unfeeling.
