Why on earth would he say that he never would have married you, had he known?
That is such an incredibly hurtful thing to say. Is he always insensitive with his words?
As far as not wanting to do the work, well, I certainly don't blame you but you know the answer to that. And the self martyr thing about knowing how important sex is to your man won't fly around here either. Let's get real. The only way to the progress road is via hard work. If you are not ready to tackle it yet, that is understandable. Only you can make that decision.
I wish I had some words of inspiration and comfort but all I can do is offer a lousy cyber hug.
