I just wanted to drop a little note to tell you to keep hope alive... old habits are hard to break and it sounds like your wife might be slipping into her old habits, maybe unconsciously testing to see if her doing that will make you change back as well.
My best advice would be to try to stay the course... words are just words but actions speak to the heart.
Maybe change things up a bit... dates have become normal... there is a set schedule, go on date, come home, ML. Where is the relaxed spontinaity? She knows what you expect at the end of a date.
If you can afford it, maybe a romantic weekend, just the two of you at a bed and breakfast, not expecting sex, just the two of you rekindling what came before sex... long walks and hand holding.
When things become routine they become chores, so think of things that might break the routine.
I hope some of this might help, I am the SS person in my relationship and am trying to put myself in the mindset of the LSD partner... in my case my partner has habitual EA with OOW and I have, as of yet, not found a way to bring his attention back to me, so I am trying the same things myself.
