CeMar, Forgive me for being blunt, but I just want to make you aware of how I (perhaps others, but I won't speak for them) perceive you. You really seem like a selfish jerk. Now, before you get your panties in a bunch over that last statement, maybe you should really consider why an anonymous person would say that to you. Perhaps I am wrong, but perhaps I am not. If I perceive you that way, then how could you possibly know that your wife would agree or not?
Before my H and I were married, we ML quite often. We saw each other only on weekends, but when we did, we ML several times a day. Once we were married it was fairly regular (a couple times a week), except when he went out to sea (he is USN). Over time, I started losing attraction to him, and looking back now, I think it was largely in part to his not meeting my needs. Therefore, I felt he was being selfish to want sex ALL the time, when I felt rejected emotionally. And he would whine and beg for it, which only disgusted me. Then he would stop asking for a week or so and start being extra nice to me. Regardless of his motives, I only saw that he was doing this for purely selfish reasons... a quid pro quo arrangement if you will. And then he would start in again with the asking for it all the time, getting madder and madder when I would refuse his advances, often saying, "but I do lots of things for you, why can't you do this for me!"
You have said before that you have tried backing off from your wife and it didn't work. Did you ever think from her side that maybe she thought you were only doing this for selfish reasons?
Have you read Gary Chapman's The Five Love Languages? If not, I suggest you do, and perhaps ask your wife to read it with you, or at ask her to at least take the wife's quiz at the end so that you can start meeting HER needs, before you think about asking her to try and meet yours.
She may be LD, but if she really felt loved by you, and wanted to show you her love in return, I am positive that she would want to try and meet your needs.
I apologize if I seem like I am being harsh on you, but I honestly believe that you cannot be meeting her needs if she is as cold and heartless towards you as you make her sound.
