I am glad things are on the upswing for you right now. And that you are realistic in the fact that it will probably come to a halt.
I really liked the question you stated. And MoJo's answer made real good sense to me. Though not saying that is the how your relationship works. But I could see that dynamic or a simular one working in my relationship. My H derives happiness from sex I on the other hand want sex when I am happy. Both revolve around happiness but comming from different angles. You could replace the word happiness with Emotional Connection also in my case. Gonna ponder this one a while.
