You write and express yourself so well. My only comment is that you may benefit from picking up & reading the 5LL book. It's a fantastic book and I only hope it is simple as Chapman makes it out to be.
As an aside, my marital sex life turned when I started when I let me desire for sex with W translated into my lifestyle. They way I act, dress, smell the whole shooting match. I felt sexier and it rubbed off on her in a big way. 5LL aint going do it alone, but it helps understand how the little things help.
Acts of Service does not appear to be your W's love language at all. Suit
