I have been on here for years, and honestly, I have not seen ANY LD women on here actually achieve success. None of them has ever become HD, the best that any have done is to become slightly less LD, except for one women that used drugs to bring back her libido. The other problem your going to have is that LD women actually believe that their POV is reasonable, when in reality it is completely unreasonable, but thats an endless aurgument. When you confront a LD person, even in a nice way, about their lack of desire, your essentially telling them that they are failures. Deep down, they KNOW this. They don't want to have to constantly confront their failure. Your wife believes your over sexed, this is common, but your not, she is UNDERSEXED. She says that people have less sex as they age, NOT TRUE. She is living in that LD world. My guess is that she gets this info from OTHER LD women, as they often hang together. She will of course ignore the comments from HD women, as they are not normal to her.
If your ok with divorce, tell her what you want, work on yourself, and give her 6 months. In 6 months, you will now the answer. If she can not change in 6 months, she never will.
