Hurt me too when I started trying to learn this. Too late to prevent my marriage from falling apart, and that is what hurt. But I took it upon myself during that time to start reading things like that so that I could learn and be better. I certainly didn't want to repeat the same mistakes if my W came back to me, or in a new R if she didn't. Pretty cliche, but when life gives you lemons... well, you know the rest.
Oh, and BTW, I can tell you for a fact that learning to establish emotional intimacy DOES pay off.
Still learning and striving not to unlearn... every day.
