I actually responded on your thread about what you told her. Women can and do have sex without any feelings, and certainly without love. Historically, women used their sexuality to accomplish or conquer various goals in their life. Some were so limited in survival skills they had to rely on their sexual abilities. It still goes on today. . Mostly, I think women have used their sexuality to control. It happens with the little housewife and goes all the way up to the White House.
True, some HD women who are in an active A can have sex with OM and her H. I won't say your W was not....(ahem).....in the mood........but based on how easily she brushed it off afterwards, and went her merry way on her "night with the girls" instead of honoring your request to be with the family, I'd say she was temp checking and getting you back in the palm of her hand. Yes, control.
I hate to tell you, but you need to write it off as nothing. In the future, please stop telling your W how she feels!!
Go back to acting as if none of this sex took place and you have not changed your stance. Do not make any comments about the sex. Just let it alone.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
