You have indicated that you need to find a way to let your wife know how important touch is to your feelings of well being. It sounds to me that you have repeatedly tried communicating this to your wife and that she either is not interested in meeting your needs or doesn't understand the desperation you now feel. I am in a the same situation - my wife indicates that she loves me and acknowledges the void in our (my) life in this area. She knows I am suffering from the lack of touch. I gather from this board that this situation is all too common.
I believe it was MPT who indicated that she was the LD spouse in a somewhat similar situation to you but the lightbulb finally went on. I am sure that there are also other success stories where the LD person finally does find it in their capacity to pay attention to their spouse's touch needs, even though they fundamentally remain LD. I wonder what it is or what event occurs that triggers this change in the LD person. I suspect the change is usually due to some event, such as a separation or serious threat of divorce that triggers a change in attitude. I believe that in our case, unless this change comes about, any form of meaningful compromise will not be possible.
