Just one thought about your 180s SD. You mentioned when you were in the "Not Getting It State" that you were going to stop doing some of those Acts of Service you had been doing. IMHO that may be a wrong move. I think you've got to be consistent and perservere here even though you're thinking why should I be the one doing all the work?
I can imagine what will go on in your Ws head if you stop those AOS. It'll probably be along these lines. "I knew it wouldn't last. He was only doing those things for sex. Its all about sex."
Its tough but you've got to hang in there. I also agree with what Tim had to say about once a week on Fridays. Its funny that all those books we read tell us that scheduled sex can be fun etc but apparently it is putting pressure not only on your W but on you as well. Maybe you need to rethink that one a bit.
And hey if its any comfort to you, at least you are getting somewhere. I'm still not receiving any passionate kisses from H. Only those lovely pecks which I am not complaining about. At least theres some improvement. Previously it was always me who had to give those pecks and usually I only get to give a peck on the cheeks but now H doesn't mind kissing on the lips and sometimes I'm not the kisser but the kissed. Even that is a baby step for me to be happy about. I get to give him a goodnight kiss and he will give me a goodmorning/goodbye kiss in the morning. Once I tried to get more, so I blocked his way and asked for a kiss. He obliged by giving a friendly peck. I put on my best pout and said "Awe, give me a proper kiss". To that, H smiled and gave me another friendly peck." Needless to say, I went to bed with tears in my eyes becos I was so dissapointed I couldn't even get a passionate kiss out of him but of course H did not know that. I couldn't start an argument or kill the moment after H looked so happy and relaxed etc. Your sitch looks a whole lot more hopeful compared to mine that I wouldn't complain if I were you. Take it slow and steady becos you ARE making progress.
