Riv-
I understand your question. In any 'regular marriage', if there was no intimacy, it is not normal. If someone were to ask you if you wanted to marry a woman who will never have sex with you... what would your answer be?
It's been 20 mos. of no intimacy with ex, since immediately after BD, as a matter of fact, it is her not wanting to be intimate that gave me the inkling that there may be a problem. At first I thought it was a problem with sex.
Intimacy is important to me, if someone said to me - your soon to be bride will have sex with you for 14 years but then not have sex with you ever again, will you still want to marry her? .... my answer would be no thank you.
I too still found my ex to be attractive, and still sleeping on the same bed with her, but not being able to be intimate or even touch her was very difficult.... which contributed to my decision to move out.
It is not an unhealthy focus. It's a basic human need.
Again, I think that my ex has divorced me quickly to be merciful. I know that a live at home MLCer is so very difficult, and cruel.
My best to you Riv. We should set up another meetup soon.
