Steve, I will add what I believe is one area that I have gotten in trouble with, in the past. And I imagine I am not the only one, is that when W doesn't want to have sex, it is not always about the H or even the state of the union. So don't take rejection so personally.
I once heard it said that "women have to have a reason to make love, men just need to have a place." Yes, there are exceptions but for the most part, I find this true.
I believe that there are several reasons that W use to want to have sex. Some involve you and many do not.
M 53 W 54, M since 98 D15, D19 8/2013 discovered EA, W maintained contact with OM until 10/14 7/2/17 W said she wanted S, 7/25/17 moved out of MBR 12/17 W says moving out 5/18, W still in home.
