Some of us wher alluding to the fact that NO amount of romantic guestures, being sexxy and attractive, thoughtfulness, love languages will be enough to make certain LD partners want to be sexually active.
Some people have it set in their mind that they just are not going to do it, and there is nothing you can do about it. You cannot convince them to be reasonable, to put someone elses needs above their own. Sometimes it is a physical and hormonal issue that makes them not WANT or not able to FEEL like it, other times it is psychological.
We have to construe that some cases it was the HD partners "fault", and many times it was NOT the HD partners "fault". That it may well be some buried evil intention ( for example the case of the woman who married the guy for the green card. And the other case the man who married her just because she was financially well off... ) that there never was love or feeling for the person in the first place. That it was a trick.
We pretty much have boiled this down to something very simple.
After a certain amount of time, even if you do not WANT to do something or don't feel it. What about your partner? Does it really make sense to go even one month without providing intimacy, or even simple physical affection to your partner.
The only case I can see not, even in a "LD" situation is if the "LD" partner was molested, raped or had a traumatic incident create the condition. In this case, they would take therapy to get over it.
I wish you all the best. But at some point to remain in certain situations, you will always be in a "martyr" position and it is IMPOSSIBLE to be in another position due to the way the other person looks at you.
