Are you trying to say that by the HD losing interest, the LD will pick up interest and fill the void? I can see that being a theoretical possibility in some marriages, but I don't see it in mine nor in HD's. That's REALLY pushing my limit of credulity.
Cobra, the only thing I'm going to say in response to this is...when I do lose interest to an extent in my marriage, be it because I'm preoccupied with other things, or I'm physically tired...what have you. I've have noticed that my H's interest in sex becomes more pronounced. I know I am not dealing with a typical LD person, but when it comes to initating he is LD...even though he's improving.
I consider this "losing interest" as dropping the rope for me...in a sense it was my way of letting go of the pressure I was putting on "us", on my H. In the past year I've lost track of how many times he's stepped up when for whatever reason I've stepped back. Oh and I'm not saying that will work for everyone either...but I also haven't seen you or HD completely drop the rope either. Dropping the rope feels too much like giving up to us HD folks...so it's very hard for us to do in order to have it really have the proper affect on our M.
