Then I am confused about this statement She agrees that she needs to work on the sex issue. At times, it is not even the lack of sex that is the issue, it is the lack of trying of the LD partner. I think if the HD partner sees some effort on the LDs side, the 'not gettin any' would not be as big of an issue.
If you are having sex one to two times a week and she would be happy with it once a month it would appear she is working on it. And the HD partner should be seeing some effort from the LD so why is it still as big of an issue? Seems like she is compromising quite a bit on her wants to make you happy. But compromise is 50-50 does not sound like you are wanting her to meet you in the middle more like you want her to do the whole 100 yards to make you satisfied. Where does that leave her? My thought 50% of the way closer to resentment land and If thats the case the getting along will not last for long before the resentment steps back in and takes over. And you are back to square one. Just my opinion.
