Jen, This happened to me and my H when our situation first started to turn around. He (formerly LD) was all over me and I was very...reluctant for some reason..? I even questioned myself and thought, Am I really as horny as I thought? Turns out that this was an adjustment period for me. It lasted about a month and then I was back to normal. It was all those things that others mentioned--I was scared to trust his changes, needed some time to process it, and quite frankly, I was just battle weary. I had been fighting this battle for the better part of our marriage. It was a constant presence in our lives. When it was gone, I was a bit lost and unsure of my new "role".
My sex drive temporarily disappeared and it confused me as much as him. Now, I still never turned him DOWN but I wasn't as enthusiastic as before. I wasn't as focused on the "will he or won't he?" as I had been for years. My whole focus of the last 5 years was no longer my focus. It was very strange and disconcerting!
But, like I said, it lasted about a month and then I started to readjust to our new setup. It is not without its problems. We still have this same conflict and I'm sure that it will dog us throughout the length of this marriage. My drive is still higher than his and some weeks we do well handling it and others it gets ugly.
But overall it is MUCH better than it was and for that I am grateful! He is a great husband who really has changed himself for the better. Keep up the good work, Jen, and this too shall pass.
