Though I know you are feeling at the very end of your rope, I think it is very good that she had admitted to the fact that she is LD and you are HD. That's step one.
I don't think it is bad that she took The Talk as a threat, as you were speaking the truth, not giving her an ultimatum. She now knows where you stand, threat or not. It will sink into her subconscious.
I think, once you calm down, that you need to do some serious thinking about how long you think you can truly hang in there. Two months? Six? A year? Commit yourself to that time frame, no matter what. That will let you off the hook in terms of "how long am I supposed to put up with this?" Believe it or not, deciding a time frame takes pressure off yourself, and in a sense, will take pressure off of her.
Then you have to get out of her if she is willing to meet somewhere in the middle... maybe by reading the book? And you have to decide if you can live with whatever it is the two of you can come up with.
In essence, I guess I am saying you need to go on a 'fact finding' mission, and try to leave the emotion out of it for now. Once you have your 'facts' in place, you can look at what is before you and come to some conclusions.
Be very, very careful of getting pregnant right now. It will change the entire scope of the playing field. And I wouldn't go down 'starting a family' road until the two of you can figure out if you can settle this between you.
I personally think that because you are in such a relatively new marriage, this is something critical to settle before bringing kids into the mix.
You are going to have to think very carefully about when and where you are going to draw your line, and you need to make sure she understands where that line is... even if it does sound like a threat. She doesn't have to take it that way. She needs to wake up and smell the coffee, and understand that if she really doesn't TRY to make some effort on her part to understand your needs, and what those needs really mean (beyond down and dirty sex), that she is going to lose her marriage.
She has the power to change, and you can help her, the book can help her, people here can help her (is she willing to get online here?), she has a variety of options.
And for the sake of your marriage, continue practicing patience (the road to patience is not the act of being patient, but through tolerance and empathy. Try to understand that she really, honestly, just doens't 'get' it right now... you getting mad at her is like getting mad at a four year old for not being able to read fluently).
It sucks being where you are, and I sooo feel for you. I know that doesn't help one whit, but this is the best I can offer. Hope some of it helps.
